  • Description: The exchange reaction between calcium ions and the carboxy groups on International Committee for Cellulose Analysis pulps, was investigated, using tritiated calcium acetate. Two relationships were established: (1) a direct relationship between the number of oxidized (carboxyl and aldehyde) groups and the number of acid soluble pentose units in each pulp, (2)an inverse relationship between the sum of the number of acid soluble pentose and alkali soluble glucose units per oxidized group and the degree of polymerization of each pulp.
