A SENSITIVE POLAROGRAPHIC TECHNIQUE

Abstract

A simple polarographic technique, based upon measuring the difference between the total current in the sample solution and the residual current in the supporting electrolyte solution at a specified time during drop life, was investigated. Concentrations, ranging from 1/1,000,000 to 1/100,000 M, of a single reducible species could be determined to within + or -4/100,000 M. A similar technique permits qualitative and quantitative analysis of mixtures containing two or more reducible species in the 1/1,000,000 M concentration range. These methods were tested with solutions of Pb(++), Cu(++), and Zn(++). (Author)
