It is the aim of the present invention to generate a method and a database of results of suitable mixtures of additives in aqueous solution, which efficiently and rapidly:
a) Reduce I 2 , RI and iodate to non-volatile iodide ions in a wide range of temperature and pH and,
b) Effectively bind the iodide ions to prevent their potential re-oxidation to volatile iodine species especially at low pH and under irradiation. This objectives are achieved by a method for a retention of iodine species in an aqueous solution, comprising the steps of:
a) adding a nucleophilic agent or a mixture of a plurality of nucleophilic agents to the aqueous solution; and
b) adding a soluble ion-exchanger agent or a mixture of a plurality of soluble ion-exchanger agents to the aqueous solution. This method provides a new way to reduce iodate, molecular iodine and also organic iodides into non-volatile iodide ions and further to bind them to suppress re-generation of volatile iodines.
