Description

The extraction of Co(III) has been studied from acetate medium by acetylacetone in CHCl3. The effect of adding different synergetic bases (S) like diisobutyl ketone, dibutyl ether, diisobutyl carbinol and tributyl phosphate was studied. The extracted species is Co(OH)2(AcAc)*2HAcAc by acetylacetone only while the species formed for the mixed extractants are Co(OH)2(AcAc)*(HAcAc) (S)n where 'n'=1 or 2. The corresponding thermodynamic parameters were determined and discussed. (author) 9 refs.; 8 figs.; 2 tabs
