Abstract: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.P
