Abstract

The electrochemical behaviour of 1, 2, 3, 4-thiatriazol-5-thiolate CS2N3 − ion in acidic solutions has been investigated. A cathodic wave has been detected, (E1/2 =−1.05V versus S.C.E., M=1.0M (NaC104) and NaCS2N3 1.00 × 10−3M). The characteristics of this wave have been investigated by D.C., A.C. polarography and controlled potential electrolysis. A mechanism which involves the interaction of CS2N3 − with mercury and cyclic regeneration of mercury has been proposed. The reduction of CS2N3 − by amalgamated zinc has been also investigated and the results correlated with the pseudo-halide electrochemical reduction.
