ABSTRACT:

Biosorption has attracted attention as a cost-effective means for the treatment of metal-bearing wastewater. While using novel biosorbents, optimization of operating conditions becomes more important for the efficiency of the process. In this study, a novel biosorbent i.e banana peel were used for biosorption of Sn2+ from aqueous media. The effect of various parameters, such as, contacts time of solution with biosorbent, temperature, pH, biosorbent dose and agitation speed were studied. A comparative study of modification of biosorbent using acid and base was also performed. It has been found that acid treated banana peel has greater biosorption capacity as compared to untreated and base treated peel. Langmuir and Freundlich isotherms were also employed to evaluate maximum biosorption capacity of untreated and chemically treated banana peel for Sn2+. This research work is of great significance with respect to practical wastewater treatment by biosorption.
