Potentiometric determination copolymers of acrylic/maleic acid in detergents and cleaning products

Polycarboxylates are used in household cleaning products, and a variety of technical applications as dispersing agents for avoiding incrustation and soil redeposition. In investigation is presented potentiometic method new in literature, simple to perform, cost effective and environmentally friendly. In alkaline medium (molecules of polycarboxylates behave as anions) anionic surfactant and polycarboxylate were titrated differentially at pH 10.5 in same titration. The first slightly distorted inflection corresponds to the anionic surfactant titration, whereas the diference beetwen first and second significantly weaker inflection relates to the carboxylate titration.
