Abstract

Chlorites are formed by reducing chlorine dioxide with arsenious acid in the presence of an alkali metal hydroxide, or alkaline earth metal oxide or hydroxide, while avoiding an excess of arsenious acid. 70-80 per cent of the arsenate produced, e.g. sodium arsenate, precipitates from the chlorite solution, and the balance is recovered by evaporation. It is reconverted to arsenious acid, for reuse, by treatment in solution with sulphur dioxide.
