Effect of Calcium Oxide-Carbonized Lophira Alata Sawdust Nanocomposite (COCLASN) in Immobilizing Cadmium and Lead in Contaminated Soil

Heavy metal polluted soil has turn out to be of global environmental concern that has involved significant unrestricted responsiveness. This study seeks to assess the effect of calcium oxide-carbonized lophira alata sawdust nanocomposite (COCLASN) in immobilizing cadmium and lead contaminated soil from Evbareke spare parts market. Contaminated soil samples were collected from Evbareke spare parts market, Benin City, Edo state Nigeria. Calcium carbide waste was collected from a panel beating workshop located at Isiohor, Edo State. The soil was physicochemical characterization. The lead and cadmium ion in soil sample was verified using Fractionation procedures. COCLASN was prepared by co-precipitation procedure. The COCLASN was characterized using FT-IR, SEM and XRD. The optimum amount of COCLASN composite for the remediation of the contaminated soil was at 3% w/w for lead contaminant and
