ABSTRACT:
The present invention relates to iodine demand disinfectants. It relates in particular to a process for preparing a polyiodide-resin for use as an iodine demand disinfectant wherein a porous strong base anion exchange resin in a salt form, is contacted with a material capable of donating a member absorbable by the resin so as to convert the resin to the polyiodide-resin. The adsorbable member is selected from the group comprising I.sub.2 and polyiodide ion having a valence of -1. The process is characterized in that conversion of the anion exchange resin to the polyiodide-resin is effected at elevated temperature and elevated pressure, the elevated temperature being 100 degrees C or higher, the elevated pressure being greater than atmospheric pressure. The present invention also relates to disinfectant substance comprising an iodine (impregnated) resin as produced by the above process.
