Description
Summary:A radiation synthesized kappa-carrageenan, chicken feather-entrapped hydrogel modified electrode (kaCCFEHM-trode) was developed to serve as working electrode in the voltammetric detection of heavy metals. The prepared metal sensor takes advantage on the presence of biofunctional chemical groups of kappacarrageenan and chicken feathers with heavy metal-binding and water-retention properties. Differential pulse anodic stripping voltammetry (DPASV) measurements using kaCCFEHM-trode showed the simultaneous detection of both lead and mercury ions. Nickel, cadmium, cobalt, zinc and copper ions all failed to exhibit binding with both modifiers.
