摘要：

Procedures were proposed for the voltammetric determination of S2- at a mercury-film electrode. They are based on the oxidation of S2- at -0.79 to -0.80 V and on the reduction of HgS, the product of the oxidation of S2-, at -0.76 to -0.96 V in a 1 M NaOH solution. The anodic and cathodic currents are linear functions of S2- concentration in the ranges from 1 x 10(-5) to 1 x 10(-4) M and from 2 x 10(-6) to 1 x 10(-4) M, respectively.
