The ability of Sarpagandha (Rauwolfia Serpentine) leaves powder (SLP) to adsorb cupper (II) from aqueous solutions has been investigated through batch experiments. In this study, the effect of contact time, effect of temperature, effect of adsorption dose, pH and initial concentration of metal ion on the bio adsorbent capacities. Kinetics of adsorption and adsorption isotherms has been studied. The various thermodynamic parameters such as free energy of adsorption (∆G°), enthalpy (∆H°), and entropy (∆S°) changes were calculated. According to the experimental results, SLP is recommended as cheapest and easily available bio adsorbent to removal of toxic heavy metal ions from industrial wastewater.
