Abstract

A rapid method has been described for the quantitative extraction of milligram amounts of Mn/II/ with 2-PRONAPOX into CHCl3. The extraction coefficient /E/ of Mn/II/ between CHCl3 and aqueous solution containing 0.2M NH4Cl shows a maximum value of E=143 at pH 10.5. The percentage extraction is better than 98% in the pH range from 9 to 11 and an equilibration time of 6 min. The effects of anions and cations have been studied. The stoichiometry of metal: reagent determined by substoichiometric extraction and slope ratio method is found to be 1∶2. The decontamination factors for most of the elements are better than 104 in the substoichiometric extraction of Mn/II/.
