Abstract

In this paper the discussion of removal of chromium (VI) from polluted water is done. Oxidation process is performed from Vincarosea Apocynaceae plants to derive sorption characteristic of Nitric Acid activated carbon. The main intent of this paper is to remove Cr (VI) from polluted solutions. XRD, FTIR and SEM-EDAX analysis are utilized based on the preparation of adsorbent using surface chemistry characteristics. Initial concentration, PH level and adsorbent dose are the effects which are determined based on the removal of chromium. Lesser extent, ionic strength and pH dependent were metal ion removal. Pseudo-second order kinetic model order is followed based on the found Kinetics data. Evaluation of activation enthalpy (ΔH*), activation entropy (ΔS*), activation Gibbs free energy (ΔG*) and activation energy are the Activation thermodynamic parameters which performs adsorption mechanism also was suggested.
