CARBOXYL CONTENT OF PULP
Pulp, Carboxyl groups, Bleached pulps, Cellulose, Ion exchange

Product Details
- Determination of the content of carboxyl groups in bleached and delignified pulps.
- Method is not applicable to unbleached and semi-bleached pulps.
- Pulp is extracted (de- ashed) with dilute hydrochloric acid, washed, reacted with sodium bicarbonate-sodium chloride solution, and filtered.
- The filtrate is titrated with 0.01 n hydrochloric acid to methyl red end point.
- Carboxyl groups represent the ion-exchange capacity of a pulp.
- Carboxyl groups contribute bonding of fibers and formation of paper
- Carboxyl groups, -cooh, are acidic groups attached to cellulose chains and are formed mainly by oxidation of cellulose during pulping and bleaching processes.
- A certain level of carboxyl groups is also associated with hemicelluloses.
