ABSTRACT
In the present study, preparation and characterization of an adsorbent made from the chemically modified Putranjiva roxburghii seeds and its applicability toward removing Ni(II) abatement from water and electroplating wastewater have been thoroughly investigated. For process optimization, various physicochemical factors affecting the adsorption process were examined. The equilibrium was achieved in 60 min for the experimental conditions accompanying the Ni(II) concentration of 50 mg L−1 with the adsorbent dose of 0.2 g in 20 mL solution. The practical utility and cost-efficiency of the adsorbent have been analyzed. The present adsorbent was proved to be efficient for the decontamination of laboratory prepared polluted water and real wastewater (electroplating wastewater of the lock industry) containing Ni(II) ions. The additional advantages of facile synthesis, low-cost, and reusability of the present adsorbent make it a novel.
