Abstract
- The simultaneous determination of thallic and thallous ions, without preliminary separation, has been achieved by differential pulse anodic stripping voltammetry at a hanging mercury drop electrode. The electrochemical activity of thallic ions in 0.2M EDTA at pH 4.5 +/- 0.2 is inhibited by the addition of 0.01% poly(ethyleneglycol) of M.W. 20,000 (PEG 20,000). When the electrolyte also contains ascorbic acid at 0.01M concentration, the sum of thallic and thallous species can be determined.
