Summary:The oxidation of H2S in sea-water is a second-order reaction, first-order with respect to sulphide and oxygen. The main products of oxidation are SO2-3, S2O2- 3, and SO2-4, formed from the oxidation of H2S with O2 over pH 4-10, 10-45 degrees C and 0-36% salinity. A kinetic model is presented for the reactions involved. The effect of Fe3+, Fe2+, Mn2+, Cu2+ and Pb2+, and alpha -FeOOH and MnO2 on the product distribution is also examined. The model can be used to estimate the intermediates formed from the oxidation of H2S with O2 in natural waters. [R.K.H.]
