Abstract
Potentiometric determinations of protonation constants and metal binding constants of the ether polycarboxylate ligands diglycolic, carboxymethyltartronic, and ditartronic acid are reported. The magnitudes of the equilibrium constants are discussed in terms of the functional groups present. Competition between ditartronic acid and nitrilotriacetic acid (NTA) for calcium(II) demonstrates that the ether polycarboxylates are particularly effective as sequestering agents in weakly to moderately acid solutions.Keywords
