Rezumat: The present study is an attempt for removal sulfides from the Black Sea water by their oxidation to sulfites or sulfates by heterogeneous catalysis. The experiments were carried out with sulfides at -3 different initial concentrations within 25 and 125 g m . The catalytic process is combined with electrochemical oxidation. Different catalysts were tested: activated carbon, zinc sulfide, cobalt sulfide and some other cobalt-containing and manganese-containing compounds. Best results were observed with spinel-type cobalt and manganese oxide included in an activated carbon matrix.
