Özet:

 





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. A linear response was found for the
heavy metals in the range from 5 to 100 mg/L. The limit of detections (LODs) of Cd2+ and
Pb2+ were 0.04 mg/L and 0.08 mg/L respectively. Manganese dioxide decorated
carboxylated graphene oxide electrode was applied to the detection of Cd2+
and Pb2+ present in different rice samples by developed
voltammetric method, and the accessed results were found to be in accordance
with that of ICP-OES.
