<abstract>In this present study, a low cost adsorbent is prepared from naturally and abundantly available Indian gooseberry seed powder which is a non-conventional adsorbent and is biodegradable. Batch experiments are carried out to investigate the effect of various process parameters such as agitation time, the adsorbent size, adsorbent dosage, initial chromium concentration and the effect of pH solution . The maximum adsorption of chromium is obtained at pH value of 2. The equilibrium data for the adsorption of chromium on Indian gooseberry seed powder is tested with various adsorption isotherms such as ‘Langmuir’, ‘Freundlich’ and ‘Tempkin’ isotherms. The Langmuir and Freundlich were found to be significant for the removal of chromium (VI) using Indian gooseberry seed powder and the maximum metal uptake is found to be 38.46 mg/g at pH value of 2. The adsorption process follows the second order kinetics and corresponding constants are obtained. In this study, Indian gooseberry seed powder is an effective and affordable adsorbent for hexavalent chromium removal from industrial waste water.</abstract>
