Popis:	The mechanism, of electrodeposition of CdS on Hg, and Pt electrodes has been studied in dimethylsulphoxide solutions by performing cyclic voltammetry at stationary electrodes and pulse polarography at dropping Hg electrodes in solutions containing both Cd(II) ions and elemental sulphur. Evidence is presented to demonstrate that sulphur is chemisorbed at these electrodes and that formation of at least a monolayer of metal sulphide is probable. As a result, formation of the initial layer of CdS involves reaction of Cd(II) ions with chemisorbed sulphur or with a pre-existing layer of metal sulphide. Data for the formation of CdS are compared with those obtained for the formation of PbS and ZnS.
