Acid-insoluble lignin in wood and pulp, Test Method T 222 om-21

Acid-insoluble Lignin in Wood and Pulp, Test Method TAPPI/ANSI T 222 om-26

This method describes a procedure which can be applied to the determination of acid-insoluble lignin in wood and in all grades of unbleached pulps. In semi-bleached pulp the lignin content should not be less than about 1% to provide a sufficient amount of lignin, about 20 mg, for an accurate weighing. The method is not applicable to bleached pulps containing only small amounts of lignin.
