This work aimed to utilize waste leather buff (WLB) as a packing filler in cellulose to produce degradable composite. Imidazolium-based ionic liquids was used to dissolve the cellulose and WLB in a coagulation bath and the resultant homogenous solution formed was casted in a clean glass plate to form cellulose/WLB composite film, washed in deionize...

The pods of Acacia nilotica were successfully utilized for the extraction of tannins using a methanol/water extraction medium. The experimental design employed for the extraction was a central composite design that enabled the evaluation of the effects of time, temperature, and methanol concentration on the dependent variables of extraction yield,...

The development of the palm oil mill has been on a downward trend recently due to world economic recession, the technological input for oil extraction is the factor that contributes to this production setback in the industry. Therefore, there a need to develop an advanced technology that will enable a spontaneous increase in the oil extraction rate...

In this study, low cost synthesis of three-dimensional mesoporous amino-functionalized silica nanoparticles (AFS-NPs) were synthesized by sol–gel method with the addition of two different silica modifiers, 3-aminopropyltrimethoxysilane (APTMS) and 3-aminopropyltriethoxysilane (APTES) to two different silica sources, tetramethoxyorthosilicate (TMOS)...

Photooxidative degradation of pre-treated Palm oil mill effluent for removal of chemical oxygen demand, biological oxygen demand and color by UV/TiO2 system has been investigated in a cylindrical glass photoreactor whose outer surface has been coated with titanium dioxide whereas the UV source has been placed inside the glass tube. The removal of t...

The contamination of water by potentially toxic elements is considered a global problem. It calls for a safe, economic and technological approach in order to curb and prevent the devastating effect of the menace on both human and the aquatic life. In the light of this background, the adsorption potential of flamboyant pod activated carbon (FPAC) fo...

This study aimed at the degradation of COD, BOD and Color present in palm oil mill effluent (POME) using UV/TiO2 system. A Statistical tool called face-centered central composite design has been run through response surface methodology by the use of design expert software to model and optimize the photodegradation process. The SEM average size of t...

This review focuses on the various types of supports used for immobilization of titanium dioxide nanomaterial catalyst for degradation of organic pollutants in wastewater. Several supports suitable to particular immobilization technique used for the degradation of pollutants in wastewater streams are explained. In general, a coating of catalyst on...

This review provides insight into various techniques utilized for the treatments of palm oil mill effluents (POME). Generally, POME treatment is achieved in two ways, these are (1) pre-treatment stages, involving majorly the reduction of oil and grease and suspended matter and (2) an advanced treatment stage, in which wastewater contaminants (e.g....

The kinetics studies of the adsorption and degradation phenomena involving tanning wastewater containing high BOD5, COD and chromium were investigated using a batch reactor and UV light irradiation under ambient conditions of temperature and pressure. Experiments were performed in a suspended ZnO-ZnFe2O4/20g AC system at natural pH of 6.93 and cata...

Tannery wastewater with high biological oxygen demand (BOD5) was treated with ZnO-ZnFe2O4 composite photocatalyst supported on activated carbon under visible light irradiation. Only 9% of BOD5 in the raw effluent were removed via adsorption on the surface of the photocatalyst in the dark for two hours. Photocatalysis with ZnO-ZnFe2O4 composite phot...

ZnO-ZnFe2O4 composite photocatalyst on activated carbon support has been synthesized and applied for the removal of chromium ions from a raw tannery effluent. Only 13% of the chromium ions in the raw effluent were removed via adsorption on the surface of the ZnO-ZnFe Photocatalysis with ZnO-in 30min and 91% in 120 fitted the Langmuir–Hinshelwood ki...

ZnO-ZnFe2O4 composite photocatalyst on activated carbon support has been synthesized and applied for the removal of chromium ions from a raw tannery effluent. Only 13% of the chromium ions in the raw effluent were removed via adsorption on the surface of the ZnO-ZnFe2O4 composite photocatalyst in the dark for 120min. Photocatalysis with ZnO-ZnFe2O4...

The effectiveness of adsorbents (unactivated and acid activated) developed from local raw materials - clay and diatomaceous earth samples - sourced from various geographical locations in northern Nigeria for use in the adsorptive bleaching of palm oil was studied. Two acids namely hydrochloric and sulphuric acids of varying strengths 20, 30 and 45%...
