Abstract

The oxidation of leuco crystal violet and of leuco malachite green by chloramine T is catalysed by iodide. Two sensitive, accurate, selective and rapid methods for the determination of iodide are proposed. Ag(I), Hg(II) and Pd(II) ions under suitable conditions inhibit the catalytic effect of iodide on oxidation of reduced form of both dyes by chloramine T. The kinetic determination of these metallic ions is useful at the trace range.
