Dissociation of Hydroxyl Groups of Cellulose at Low Ionic Strengths

摘要

According to Donnan equilibrium theory,the dissociation of the hydroxyl groups of cellulose (mercerized cotton) or alkaline adsorption can be trea-ted as a function of the pH and ionic strengths of the external solution,and of the amount of fixed anionic groups in cellulose,by using 1:1- and 1:2-electrolytes as a neutral salt to adjust the ionic strength.
