SORPTION OF HYPOIODOUS ACID ON ACTIVATED CARBON

In spite of good adsorption characteristics of activated carbon for mo lecular iodine, from water solution, problems arising due to complexit y of chemistry of iodine and hydrolysis as well as influences of other relevant factors in water solutions which easily change the equilibri um concentrations toward domination of species with lower absorbabilit y. Sorption of hypoiodus acid as predominant chemical form of iodine i n neutral and weak alkaline solution within the range of micro concent rations has been studied in great details. In the experiments sorption of hypoiodous acid from water solutions on activated carbon with surf ace area of 1000 m(2)/g, under static and dynamic conditions, has been performed Isotherms on various temperatures (25 degrees C, 50 degrees C, 70 degrees C) hm been obtained. Parameters of the sorption are det ermined and mechanism of adsorption of hypoiodous acid molecules on ac tivated carbon has been discussed.
