Sažetak
Sulphur electrochemical speciation techniques were applied to understand the chemistry and cycling of sulphur in two meromictic lakes: seawater lake, Rogoznica Lake (Croatia) and crater lake, Pavin Lake (France). Using a cathodic stripping cyclic and linear sweep voltammetry we aimed to make distinguish between free and metal sulphide species in the anoxic deep layers. 90% of determined sulphur species in the anoxic bottom water of Rogoznica Lake are in the form of free sulphide, while opposite result was observed in the Pavin Lake. There was no presence of free sulphide detected ; all sulphur was in the form of metal sulphide species, which regarding a prevalence of Fe can be ascribed to the presence of FeS.
