Solvent extraction of Co(III) with 1,2,3-benzotriazole into n-butanol
Description
A new and rapid method was developed for the quantitative extraction of Co(III) with 1,2,3-benzotriazole into n-butanol. The extraction coefficient value of Co(III) between n-butanol and an aqueous 5% solution of 1,2,3-BT in 2M sodium acetate-acetic acid buffer showed a maximum value of E=280 at pH 8.5. The effect of various other parameters on the extraction coefficient of Co(III) such as solvents, anions, cations etc. was also studied. The stoichiometry of the metal:reagent determined by the method of substoichiometric extraction and slope-ratio method was found to be 1:2. The separation factors studied for most of the elements were found to be better than 103. (author) 6 refs.; 2 figs.; 2 tabs
