Complexons are widely used for washing out heat and power engineering equipment. Ethylenediaminetetraacetic acid (EDTA) and its salts, which are used for these purposes, suffer from a number of drawbacks: poor solubility at low pH values, and relatively narrow pH ranges in which the metal complexes are stable. These drawbacks are avoided to a considerable extent by the use of complexons containing alkylphosphonic groups, and in particular hydroxyethylidenediphosphonic acid (HEDP). The purpose of the present work was to determine, on the basis of kinetic relationships, the factors influencing the rate of the controlling step in dissolution of magnetite, one of the components of scale deposits, in HEDP solutins and to find the optimal conditions of Fe/sub 3/O/sub 4/ dissolution in this organophosphorus complexon.
