The paper considers the possibility of determining platinum metals in mineral raw materials by stripping voltammetry on a graphite electrode modified by metals. Stripping voltammetry method is characterized by low determination limit, wide intervals of determined content and high sensitivity. As a result of the research the conditions for the determination of gold, platinum and palladium by stripping...
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...
