ABSTRACT Batch and column kinetics of methylene blue and red basic 22 adsorption on CaCl(2) treated beech sawdust was investigated, using untreated beech sawdust as control, in order to explore its potential use as a low-cost adsorbent for wastewater dye removal. The adsorption capacity, estimated according to Freundlich's model, and the adsorption capacity coefficient values, determined using the Bohart and Adams' bed depth service model indicate that CaCl(2) treatment enhanced the adsorption properties of the original material.

    ABSTRACT: The ash of C. polygonoides (locally called balanza) was collected from Lakki Marwat, Khyber Pakhtunkhwa, Pakistan, and was utilized as biosorbent for methylene blue (MB) removal from aqueous solution. The ash was used as biosorbent without any physical or chemical treatment. The biosorbent was characterized by using various techniques such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The particle size and surface area were measured using particle size analyzer and Brunauer-Emmett-Teller equation (BET), respectively. The SEM and BET results expressed that the adsorbent has porous nature. Effects of various conditions such as initial concentration of methylene blue (MB), initial pH, contact time, dosage of biosorbent, and stirring rate were also investigated for the adsorption process. The rate of the adsorption of MB on biomass sample was fast, and equilibrium has been achieved within 1 hour. The kinetics of MB adsorption on biosorbent was studied by pseudo-first- and pseudo-second-order kinetic models and the pseudo-second-order has better mathematical fit with correlation coefficient value (R (2)) of 0.999. The study revealed that C. polygonoides ash proved to be an effective, alternative, inexpensive, and environmentally benign biosorbent for MB removal from aqueous solution.

    ABSTRACT: The increase in number of modern industry in the twenty-first century that uses dye and ends up disposing it into the environment and water bodies causing diseases and other environmental risks to both aquatic life and human being is alarming. In response to the increasingly stringent discharge standards and discharge fee, textile industries must upgrade the performance of their wastewater treatment facilities with primary effort on reducing chemical oxygen demand and color. This paper presents a review of dye adsorption using activated carbon prepared from different sources and environmental implications. Also, its major challenges together with future prospects are summarized and discussed. Conclusively, the production of activated carbon from waste biomass for adsorption of these dyes is of great importance in pollution control and environmental conservation.

    ABSTRACT: In the present study, Plackett–Burman design has been used to identify the significant factors affecting the removal of basic dyes using agricultural waste, sugarcane bagasse (natural sugarcane bagasse). The effect initial dye concentration and sorbent dosage were identified to be the variables responsible for affecting the percentage uptake of Basic Blue 3 (BB3) and Methylene Blue (MB) from aqueous solution. Meanwhile, none of the studied variables were found to be significantly affecting the percentage uptake of Basic Yellow 11 dye. The interaction between the factors and their optimum levels for maximum percentage uptake of dyes were determined using Response Surface Methodology. Both models were highly significant with correlation coefficients (R2) of 0.9947 and 0.9967 for BB3 and MB dye solutions, respectively. For BB3, the percentage uptake of 98.59 was obtained with optimized conditions at 50 mg L−1 initial dye concentration and 0.13 g sorbent dosage. Whereas for MB, under the optimum of 72 mg L−1 of initial dye concentration and 0.18 g of sorbent dosage, the percentage uptake was recorded to be 95.19. The experimental values agreed well with the predicted values with percentage errors less than 3%.
