Figure Lengend Snippet: ( A ) Metal concentration in the NiMH battery leachate composed of 27.0 wt.% CH3COOH aqueous solution and in the 73.0 wt.% [P 44414 ]Cl + 27.0 wt.% CH 3 COOH mixture (t = 24 h, T = 323 K, S/L = 0.1). ( B ) Co(II) selectivity (S) in the biphasic [P 44414 ]Cl + CH 3 COOH + H 2 O from the principal metals in the NiMH leachate. The total composition of systems 1 and 1 * are provided in ; individual metal distribution coefficients are available in .
Article Snippet: The ionic liquids [P 4444 ]Cl (95.0 wt.%), [P 44414 ]Cl (95.0 wt.%) were obtained from Cytec industries, [N 4444 ]Cl (97.0 wt.%) from Sigma-Aldrich (St. Louis, MO, USA)and [C 14 mim]Cl (98.0 wt.%) from Iolitec (Heilbronn, Germany).
