| Abstract: | The Voltammetric behaviour of amaranth at mercury membrane elec- trode based on the silver has been studied in this paper.It was found that amaranth gaves a cathodic peak sensitively with the potential of -0,24V at pH 4.0 in aqueous solution.The mercury membrane electrode based on the silver was better in duplicability and life to be used.The peak current depends on the concentration of amaranth linearly from 10 to 100 ppb. |
