Description A rapid method has been developed for the solvent extraction separation of manganese (II). At pH 5 - 8, 2.5 x 10(-3) mol/l Crypt and 221 in chloroform quantitatively extracts manganese with 1.5 x 10(-3) mol/l Erythrosin as the counter ion. From the organic phase it was stripped with 0.5 mol/l hydrochloric acid, and was determined by atomic absorption spectroscopy at 279.5 nm in an air-acetylene flame. Manganese was separated from iron(III), zinc, cadmium, lead, cobalt, nickel, thallium(I), which were generally encountered in an aquatic environment. The method was extended for analysis of manganese from aerosols, sediments and effluents.
