Abstract:
The content of carboxylate ions in marine sulfate polysaccharide 911 was determined by conductometric titration. In the mean while, the sample was transformed with cation exchange resin,the molar ratio of sufate ions to carboxylate ions was determined. The results showed that conductometric titration is a simple,rapid and accurate method.
