    Abstract

    Interactions of certain stainless steels (S30400, S31600, S31803, S32304) and sulphur anions, separately and in combination, at concentrations typical of kraft liquors were investigated using XRF and CER techniques. IC, ISE and ABC titration were applied in the modelling of behaviour of the sulphur anions. Nickel and sulphur enriched to the steel surfaces in all experiments. Abilities of molybdenum and chromium to remain in the surfaces appeared to be better than those of iron. Adhesion of sulphur onto austenitic grades was probably stronger than that of the duplex grades. Sulphide and combination of sulphur anions formed durable films, but films formed by thiosulphate possessed some gliding properties. For the solution, real amount of the sulphide was less than the added amount. Thiosulphate had a tendency to convert into sulphite.
