Micro-determination and separation of manganese using a liquid ion exchanger

Abstract

A sensitive and selective method for the micro-determination of manganese has been developed involving the extraction of the wine-red manganese-benzohydroxamic acid (BHA) complex with Aliquat 336 liquid ion exchanger, and the optimum conditions have been established. Kinetic and stability studies on the complex were carried out. The extracted metal can be quantitatively eluted with 0.25 M hydrochloric acid, thus rendering the method applicable for the concentration, separation and determination of manganese in samples containing very low levels of the metal.
