【Abstract】 This paper put forward the method of oscilloscope polarogram titration to determine the content of cation active agent octadecyl benazone enka-anmoniurnu、octadecyl chloropyridine、cetyl bromo-pyridine. Compare the data resulted from this method with that from potention titration,there is little difference between the two. This proves that both the precision andthe accuracy of this method are good,and it has the character of accuraly、 high-speed、 simplicityand convenience、sensitivity and economy.更多还原
