Abstract

The voltammetric behavior of amaranth at a mercury thin film electrode on a silver substrate was studied in this paper. It was found that amaranth gave a sensitive reduction peak with the potential of -0.24 V at pH 4.0 in aqueous solution. The mercury thin film electrode on a silver substrate gave good reproducibility and useful life time. The peak currents depended linearly on the concentrations of amaranth from 0 to 100 ppb.
