摘要：

Potentiometric titration data for cellulose pulps are analysed by various theoretical techniques. The cellulose surface of woodpulps is surprisingly tractable and the data can be fitted by a simple double-layer model. Apparent dissociation constants for the acidic group present and the extent of the gel layer can be obtained by using equations applicable to polyelectrolyte gels.
