Abstract

The equilibrium and kinetics of copper extraction from water solutions of copper(II) perchlorate into chloroform by 8-quinolinol, 2-methyl-8-quinolinol, six 7-alkenyl-8-quinolinols (with C₃ to C₁₂ side chains) and by 7-(p-tert.butylbenzyl)-8-quinolinol were measured. The data were treated by previously derived models which take into account the complex nature of the extraction process. The equilibrium data were expressed as extraction constants K_ex, the rate data as the rate parameter Θ and initial extraction rates J⁰, respectively. The influence of the position, size and structure of the substituents on these parameters is discussed. A strong effect of the position of the double bond C=C in the side chain was found.
