Electrochemical Detection of Cadmium and Lead in Rice on Manganese dioxide Reinforced Carboxylated Graphene Oxide Nanofilm

Ali Osman SOLAK

Manganese dioxide decorated carboxylated graphene oxide (Mn-GO-COOH) attached onto the glassy carbon (GC) electrode to develop a new method for the simultaneous determination of Cd2+ and Pb2+ ions in rice samples. Graphene oxide (GO) was attached on 4-aminophenyl covalently modified glassy carbon surface via amide reaction. As-prepared modified material was characterized with XPS, SEM and electrochemical methods. A novel differential pulse anodic stripping voltammetric (DPASV) method was developed for the simultaneous determination of Cd2+ and Pb2+ on the GC/Mn-GO-COOH nanoplatform electrode. ...Daha fazlası
