It was shown that potassium xanthate can be determined in aqueous solutions by cathodic stripping voltammetry at a silver electrode. The detection limit for potassium xanthate electroaccumulated for 5 min and determined under the optimum conditions in the Britton buffer solution with pH 11.98 was 1.8 × 10−5 M at a relative standard deviation of 5%; the upper boundary of the analytical range was 5 × 10−4 M at a relative standard deviation of 1.5%.
