R. Prabakaran, S. Arivoli

Abstract

The removal of selective metal ion like Ni2+ ion in aqueous solution were investigated by adsorption process on low cost activated carbon prepared from Thespesia Populnea bark(TPC).In this study, the effect of temperature, pH and initial concentration of metal ion on the biosorption capacities, Kinetics of adsorption and adsorption isotherms have been studied. Also various thermodynamic parameters such as , and were calculated. According to the results, Thespesia Populnea bark is recommended as cheapest and available bio adsorbent to removal of toxic metal ions from industrial waste water.
