Tanning industries are one of the main economic activities in Bangladesh. It has been well documented that wastewater discharged from tanneries without appropriate treatment results in detrimental effects on the ecosystem. No ecotoxicity evaluation of any aquatic environment in Bangladesh has been conducted so far. In this study a battery of toxicity bioassays and chemical analysis were carried...

Reaction kinetics of benzid ine oxidation with ClO 2 in the wastewater was investigated systematically by detecting concentrations of benzid ine with HPLC at regular intervals. The results show that the reaction was firstorder with respect to both ClO2 and benzid ine, and the entire reaction was of second-order. Under condition of pH 6.5 and water temperature 298K, the second-order reaction rat...

Development of nanofilters with the ability to remove toxic metal ions from effluent wastewater will be immense help leather industry. In this study, fibrous nanofilter (FNF) was prepared using microfibrillated cellulose and tea leaf microparticles blended in poly (vinyl) alcohol. FNF analysed for its efficacy hazardous metals tannery wastewater. The had promising traits tensile strength (19.24...
