REMOVAL OF LEAD (II) FROM WASTEWATER USING PEAS HUSK WASTE

Abstract

This research is to study the possibility of using the peas husk, as biosorbent alternative low-cost to treat lead from wastewater because of its widespread and toxic application in the industrial products. Peas husk was obtained from waste plant peas on farms or food. Powdered peas husk was used to absorb lead ions from solutions simulation in batch experiments. The effects of contact time, initial metal concentration, dose and pH on the simultaneous adsorption of lead were studied. Experimental results concluded that better absorption efficiency was obtained within 30 minutes of connection time. Maximum removal of lead on the peas husk was achieved when pH is 4 which is about 96.9 %. Surface morphology was observed peas husk before and after application of adsorption process of solutions of lead under Field Emission Scanning Electron Microscopy (FESEM).
