Abstract

It is found out based on the potentiometric and spectrophotometric titration that acid-base properties of lignin are linearly dependent on its weight-average characteristic, pKa values of Bjorkman lignin are determined for conjugate (containing phenolic groups with ?-carbonyl group in n-position) and inconjugate (containing phenolic groups with no ?-carbonyl group in n-position) structures in water medium.
