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 Kex, 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.
