Abstract: Application of Syzygium cumini seeds as bio sorbent for the removal of Acid Violet 4BS dye from aqueous solution and textile industry wastewater was investigated. Batch experiments were carried out to determine the effect of pH, particle size, bio sorbent dose, contact time and initial dye concentration. Characterization of bio sorbent was also done by SEM and FTIR. Maximum dye bio sorption of 91.20% was achieved at pH 2.0, particle size 212µm, bio sorbent dose of 1g/L, contact time of 60mins and initial concentration of 50mg/L. The equilibrium bio sorption data fitted well to Langmuir than Freundlich isotherm models with Langmuir monolayer bio sorption capacity of 20.0 mg/g and Freundlich bio sorption capacity of 11.78 (mg/g) (mg/L) 1/n . The bio sorption results in this study indicated that Syzygium cumini seeds are attractive option for removing acidic dyes from the wastewater.
