Determination of Gold by Stripping Voltammetry in Platinum Gold Ore Mineral Raw Materials on Grafite Electrode Modified by Bismuth

The paper considers the possibility of determining the gold (III) by stripping voltammetry on graphite electrode modified by bismuth. It is shown the modification of the graphite electrode by bismuth increases the sensitivity of detection of gold in 2 times. The comparison of the results of gold determination by stripping voltammetry and by atomic absorption is presented. The advantages of stripping voltammetry on a graphite electrode modified with bismuth for gold determination are given.
