Expulsion of Zn from the Downstream of Metal Plating Effluent onto Modified Agricultural Adsorbent Prepared from Peanut Shell

Abstract

Present work deals with the removal of Zinc (Zn) from metal plating industry effluent (MPE) using peanut husk as a modified agricultural adsorbent (MAA). The adsorption of zinc from metal plating effluent has been investigated along with various adsorbent parameters. The MPE was investigated for various parameters like pH, adsorbent doze dose, contact time, initial zinc concentration and temperature. The maximum removal efficiency of zinc was found to be (75.85 %) at pH 3.5 and time 250 min). The sludge obtained after adsorption has been filtered followed by drying which can be used in a boiler furnace as a fuel.
