Abstract
A method for the routine radiochemical determination of carboxylic acid groups in polysaccharides is described. The procedure is based on sodium borotritide reduction of the product of the reaction between water-soluble carbodiimide derivatives and carboxyl groups on the polysaccharide. Carboxymethyl-cellulose and hyaluronic acid were used as test polysaccharides.
