    ABSTRACT: The adsorption of FD&C red 2 and FD&C yellow 5 onto chitosan films was evaluated by equilibrium isotherms, thermodynamics and kinetic studies. The effects of temperature (298–328 K), initial dye concentration (50–300 mg L−1), stirring rate (50–350 rpm) and contact time (0–120 min) were investigated at pH of 2.0 and 100 mg L−1 of chitosan films. The dyes concentration was determined by spectrophotometry. Freundlich and Langmuir models were used to represent the equilibrium data. The Langmuir model was the more adequate to represent the equilibrium data (R2 > 0.99 and average relative error <2.50%) and the maximum adsorption capacities were 494.13 mg g−1 and 480.00 mg g−1 for FD&C red 2 and FD&C yellow 5, respectively, obtained at 298 K. The RL values ranged from 0.044 to 0.145. The adsorption was exothermic, spontaneous and favorable. For the FD&C red 2, 90% of saturation was attained at 120 min and the Elovich model was the more appropriate. For the FD&C yellow 5, 95% of saturation was attained at 20 min and the pseudo first–order model was the more adequate to fit the kinetic data. Chitosan films were easily separated from the liquid phase after the adsorption process, providing benefits for industrial applications, and its application range can be extended for azo dyes.

    ABSTRACT: In this report, spectrophotometric, kinetic and structural analysis has been carried out for the formation of cobalt nanoparticles (CoNPs) using 4-aminophenol as reducing agent. The localized surface plasmon resonance band (SPR) of cobalt nanoparticles in the UV-vis spectrum is used to determine the rate of formation of cobalt nanoparticles and assess the beginning of the oxidation process. The effect of cobalt nitrate, 4-aminophenol and TTAB concentration was investigated on the growth rate of cobalt nanoparticles. CoNPs were characterized by means of UV-vis, field emission scanning electron microscope (FESEM) and energy dispersive spectroscopy (EDS). The data obtained in this work provide valuable information on the rate of reactions at the nanoscale.

    ABSTRACT: Magnetite (Fe3O4) and Zn0.5Fe0.5Fe2O4 nanoparticles (NPs) were synthesized via sonochemical coprecipitation reactions with moderate ultrasound irradiation. The structure and crystalline=particle sizes of the synthesized NPs were determined by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM), and the magnetic properties were measured by vibrating sample magnetometry (VSM). The results show that NPs of smaller size and narrower size distribution can be synthesized via coupling of moderate ultrasound irradiation in coprecipitation reactions. In addition, magnetic NPs prepared in the presence of ultrasonic irradiation exhibit improved magnetic properties.

    ABSTRACT: In this paper, one dimensional transient moisture and solute diffusions in the spherical geometry during osmotic dehydration was modeled by exact analytical method and two approximate models. Approximate models have been developed based on a parabolic and power law profile approximation for moisture and solute concentrations in the spatial direction. The proposed models were validated by experimental water loss and solid gain data obtained from osmotic dehydration of spherical cherry tomatoes in NaCl salt solution. Experiments were conducted at six combinations of two temperatures (30 and 40°C) and three solution concentrations (10%, 18% and 25% w/w). A two-parameter model was used to predict moisture loss and solute gain at equilibrium condition, and moisture and solute diffusivities were estimated by fitting the experimental moisture loss and solute gain data to the Fick's second law of diffusion. The values of mean relative errors for exact analytical, parabolic and power law approximation methods respect to the experimental data were estimated between 6.58 and 9.20%, 13.28 and 16.57% and 5.39 and 7.60%, respectively. Although the parabolic approximation leads to simpler relations, the power law approximation method results in higher accuracy of average concentrations over the whole domain of dehydration time.

    ABSTRACT: Recently, due to an increase in production demand in nuclear and oil and gas industries, the requirement to migrate toward larger pipe sizes for future developments has become essential. However, it is interesting to note that almost all the research on two-phase gas–liquid flow in vertical pipe upflow is based on small-diameter pipes (D ≤ 100 mm), and the experimental work on the two-phase gas–liquid flow in large-diameter (D > 100 mm) vertical pipes is scarce. Under the above circumstances, the application of modeling tools/correlations based on small-diameter pipes in predicting flow behavior (flow pattern, void fraction, and pressure gradient) poses severe challenges in terms of accuracy. The results presented in this article are motivated by the need to introduce the research work done to the industries where the data pertaining to large-diameter vertical pipes are scarce and there is a lack of understanding of two-phase gas-liquid flow behavior in large-diameter (D > 100 mm) vertical pipes.The unique aspect of the results presented here is that the experimental data have been generated for a 254-mm inner diameter vertical pipe that forms an excellent basis for the assessment of modeling tools/correlations. This article (i) presents the results of a systematic investigation of the flow patterns in large-diameter vertical pipes and identifies the transition between subsequent flow patterns, (ii) compares it directly with the existing large- (150 mm) and small-diameter data (28 mm and 32 mm) in the same air–water superficial velocity range, (iii) exemplifies that the existing available empirical correlations/models/codes are significantly in error when applied to large-diameter vertical pipes for predictions, and last (iv) assesses the predictive capability of a well-known commercial multiphase flow simulator.

    ABSTRACT: Pressure distribution, caused by ultrasonic wave propagation, has the crucial effect on efficiency of sonoreactor for crude oil upgrading. In this study, acoustic pressure distribution was computed by numerical solution of acoustic wave propagation equation in crude oil sonoreactor. By analyzing of numerical simulation results, optimum geometrical and operational parameters, comprising type and probe size, probe depth in bulk of crude oil, dimensions, shape of reactor, frequency, and sound power, were discussed for the highest possibility of cavitation, chemical, and physical changes. Moreover, the effect of probe location on pressure distribution was investigated. The results show the important effect of probe location on pressure distribution due to change of wave reflection angles.

    ABSTRACT: The inhibition effect of glutamic acid (Glu) towards corrosion of aluminum in 0.1 M HCl solution was investigated using linear polarization (LPR), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. Polarization curves revealed that Glu acted as a mixed type inhibitor. The values of polarization resistance obtained by LPR and EIS were consistent in showing that inhibition efficiency increased with increasing concentration of Glu. The inhibition occurs by adsorption of Glu on the metal surface and evidence of this was given by the equivalent circuit analysis of EIS results. The adsorption process was found to obey the Hill de Boer isotherm with a standard free energy of adsorption of -60.45 kJ mol-1. Surface analysis by means of X-ray photoelectron spectroscopy (XPS) was performed to provide chemical characterization of the adsorbed layer. The N 1s spectrum showed the presence of ionized (NH3+ ) and neutral (NH2) amino group. The corrosion inhibition was attributed to a chemisorption process with Glu molecules forming a stable chelate on the metal surface

    ABSTRACT: The study investigates the effectiveness and energy conservation potential of a high rate hybrid up-flow anaerobic sludge blanket (UASB) reactor treating a combination of domestic waste activated sludge and distillery's spent wash. Analysis of the results revealed good organic removal efficiency at a hydraulic retention time of 5 days. However, the economic feasibility was not studied. This corresponded to an average percentage COD removal of 65%, an average percentage BOD removal of 40.41%, and an average total suspended solids removal of 87%. Biogas volumes were measured using a water displacement technique, and a steady biogas production rate of 2 L/day was attained after 71 days of substrate and nutrient addition. Two well-known mathematical models were used to estimate biogas volume. Hill's model was found to be in better agreement with experimental results; it is within ±10%. Based on the results obtained, the construction of a hybrid anaerobic sludge blanket reactor at a water treatment facility for the biodegradation of distillery spent wash and domestic waste to produce biogas and energy is unquestionably a lucrative and sustainable venture.

    ABSTRACT: Prediction of the behaviour of convective mixing and the effectiveness of this mechanism is essential for permanent sequestration of CO2 in deep saline aquifers. Simulation of the diffusion-convection mechanism at a large scale is very expensive and time-consuming; therefore scaling relationships can be used to find suitable candidates for storage sites. In this study, scaling analysis is performed for the convective mixing of CO2 in saline aquifers based on experimental results. The scaling relationships are presented for the prediction of convective dissolution behaviour. In the presented scaling analysis, different systems with a wide range of Rayleigh numbers were used. All experiments were conducted in a dissolution cell with different ranges of grain sizes. The pressure decay data are used to determine the dissolution rate of CO2, Sherwood number, and convective flux. In addition, the fraction of ultimate dissolution is calculated for each experiment to investigate the mixing regimes (convective mixing and diffusive mixing). The results indicate that the mixing of CO2 in water can be approximated by a scaling relationship for the Sherwood number and convective flux. These relations can be used in the implementation of large scale CO2 storage in deep saline aquifers.
