The polyelectrolyte titration technique was used to investigate the relationship between bulk and surface charges for various pulps and treatments. The total and surface charge content is different for hardwood and softwood pulps; however, the charge ratio is the same. Mechanical pulping gives a higher charge ratio than chemical pulping. Even though the amount of charges are changed during different bleaching sequences for chemical pulp, the charge ratio is not affected because the bleaching process is non-surface selective. fn order to change the charge ratio for chemical pulp, beating or surface carboxymethylation can be performed.
