Polarographic study of inhibitors and catalysts for the reaction of dissolved oxygen with sulphite ion.
Oxygen reduction waves are utilized to determine the inhibition effect of some reagents commonly added in polarographic work, on the reaction of dissolved oxygen with sodium sulphite in neutral and alkaline supporting electrolytes. Alkali metal hydroxides, EDTA, TEA, ethanol and methyl cellosolve inhibited the reaction to various extents. In this work, it appeared that some metallic ions, such as cobalt(II) and manganese(II) can catalyse the oxygen-sulphite reaction, enabling wider application to be made of sodium sulphite for de-oxygenation of neutral and alkaline supporting electrolytes containing inhibitors.
