摘要：Application of Annona squamosa bark as biosorbent for the removal of Basic Black 2XRL dye from aqueous solution and leather industry wastewater was investigated. Batch experiments were carried out to determine the effect of pH, particle size, biosorbent dose, contact time and initial dye concentration. Characterization of biosorbent was also done. Maximum dye biosorption of 78.46 % was achieved at pH 7.0, particle size 212μm, biosorbent dose of 0.8 g/L, contact time of 12 0 min and initial concentration of 50 mg/L. The equilibrium biosorption data fitted well to pseudo second order and Langmuir than Freundlich isotherm models. The biosorption results in this study indicated that Annona squamosa barks are attractive option for removing basic dyes from the wastewater
