Voltammetric studies with different electrode systems. Part IV. Determination of silver by using a silver-molybdenum system

Abstract

Silver is determined at trace level (1 to 100 p.p.m.) in organic solvents and alkalis by using a semi-micro cell incorporating a silver-molybdenum system. The determination is carried out on a differential cathode-ray polarograph. With this electrode system only silver and mercury cations were reduced and the peak potentials were well separated. No chemical separations are involved. Factors affecting the silver reduction in organic solvents are discussed.
