General procedure for the determination of trace amounts of iodine in natural water samples of unknown composition by spectrophotometric titration

Maria Pesavento  and  Antonella Profumo  

Abstract

Concentrated hydrochloric acid is added to samples of natural waters containing 2 × 10–7–5 × 10–5M iodine and the solutions are then oxidised with hydrogen peroxide on a boiling water-bath. They are then reduced with sodium sulphite, which is subsequently removed by bubbling a stream of inert gas through the solution. All of the inorganic iodine, now present in the solution in the –1 oxidation state, can be titrated spectrophotometrically with standard potassium iodate solution, following a method previously described in which interferences from oxidants and reductants are eliminated.
