[The study of amphoteric surfacant sensitizing catalytic spectrophotometric determination of Mn (II)].

Abstract

A new catalytic spectrophotometric method for the determination of trace amount of Mn(II) has been developed. The method is based on the oxidation of thionine by potassium periodate in the presence of nitrilo triaceticacid as an activator and amphoteric surfactant dodecyl dimethylamino acetic acid(DDMAA) as enhancing agent. Dodecye dimethylamino acetic acid… (More)
