In this study, waste hairs of the conventional (PPC) and enzymatic (PPE) unhairing process of tannery were used as adsorbents to remove lead from an industrial effluent. Waste hairs were treated with acid hydrolysis. The adsorption experiment type Batch was performed to examine the effect of pH on the adsorption and also to investigate the mechanism of adsorption for which studies adsorption isotherms and the adsorption kinetics of Pb (II) was performed on the two types of treated hairs. The results showed that adsorption of Pb(II) was pH dependent with the optimum pH of 7. Isotherm studies showed that experimental data match the pattern of the Langmuir isotherm for the case of treated hairs enzymatic unhairing process (PTPE) and the Freundlich isotherm model in the case of treated hairs conventional unhairing process (PTPC). From this it could find that the maximum adsorption capacity was 321.20 mg Pb (II)/g of bioadsorbent to PTPE and 0.962 mg Pb (II)/g of bioadsorbent to PTPC, due to which it was decided that the most efficient adsorbent (PTPE) It will be analyzed for kinetic studies. These studies also showed that the kinetic reaction model pseudo-second order best describes the adsorption process. Moreover, continuous adsorption process on PTPE evaluated. Finally, the study showed that residues of hairs enzymatic unhairing process can be used as effective adsorbents for the removal of divalent lead.
