Application

HEDP can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. In other words, HEDP acid can react with metal ions in the water system to form a hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, HEDP shows good synergistic effects. Hydroxyethylidene diphosphonic acid can be also used as chelating agent in the textile industry.
