Demand-type disinfectants are prepared from strong base anion exchange resin beads and elemental iodine. The resin is in the iodide form, and the iodine is applied with a water carrier which is recycled in contact with the resin and the stoichiometric amount of iodine to form the desired polyiodide (viz. I 3 , I 5 , or mixtures thereof) A homogeneous product of pre-determined polyiodide content is obtained. |
