Abstract Interference from Pb(II) and T1(I) in the differential pulse polarographic determination of arsenite is eliminated by chromatography on a chelating ion exchange resin. Strong ligands prevent the removal of Pb, but addition of Cu(II) before chromatography results in successful analysis by dissociating the Pb complex. Since the interfering ions are removed from solution, greater than a 1000-fold mass excess of Pb and T1 can be tolerated.
