- 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 (k1, k2 Rmmax, tmax, Jdmax and Jamax) was also investigated. The membrane entrance rate, k1, and the membrane exit rate, k2 increased with increasing temperature and stirring rate. For the maximum membrane exit flux, Jamax, 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.
