Interactions between Chlorolignin and Polysulfone Ultrafiltration Membranes

Abstract
Interactions between chlorolignin and polysulfone ultrafiltration membranes have been studied by means of direct adsorption measurements and ultrafiltration experiments. The electrical properties of the membrane (zeta potential) and the chemical and physical properties of aqueous chlorolignin have been determined. Phenomena and parameters affecting separation of chlorolignin from aqueous solutions at various pH levels are discussed.
