Case Study

Adsorption Removal of Acid Brown 265 by Biochar from Tannery Wastewater

Mim S, et al. Environmental Monitoring and Assessment, 2023, 195(6), 695.

Acid brown 265 can be used as a representative dye for research on contaminants in tannery wastewater. Biochar extracted from tannery lime sludge has been shown to have good removal efficiency for acid brown 265 dye.
· The efficiency of dye removal by batch coagulation-adsorption-oxidation of this material was studied.
· The dye efficiency, BOD (biochemical oxygen demand) and COD (chemical oxygen demand) efficiency of the biochar material reach 94.9%, 95.7% and 93.5% respectively.
· The dye adsorption behavior of biochar was in good agreement with the Freundlich isotherm (R2 = 0.9987) and pseudo-second-order (R2 = 0.9996) kinetic models.
