- Abstract
When titrating chlorides in N-acylamino acid anionic surfactants by argentometry, the presence of N-acylamino acid anionic surfactants has caused a serious lag in the end point of the titration and affect the accuracy of the experiment. To solve this problem, the samples were pretreated to eliminate the interference, and the accuracy of different titration methods was explored. The results show that the direct titration method using potassium chromate indicator is more suitable for determination of the chloride content in N-acylamino acid anionic surfactants, which can meet the requirements of manufacturers for chloride content monitoring.
