Abstract
The transport of Cu(II) ions from an aqueous solution into an aqueous receiving solution through a bulk liquid membrane containing a dithiophosphonate derivative (1) as a carrier was examined. The kinetic parameters were analyzed assuming 2 consecutive, irreversible first-order reactions. The influence of temperature and stirring rate on the kinetic parameters (k_1, k_2, R_m^{max}, t_{max}, J_d^{max} and J_a^{max}) was also investigated. The membrane entrance rate, k_1, and the membrane exit rate, k_2, increased with increasing temperature and stirring rate. For the maximum membrane exit flux, J_a^{max}, the activation energy was determined from the slope of the linear Arrhenius relationship to be 8.70 kcal mol^{-1}, which indicates that the process is controlled by species diffusion.
