Abstract
In this article, a calix‐oligomer derivative is used (1) as a carrier to transport Hg2+ ions from an aqueous solution into an aqueuos receiving solution. The kinetic parameters were analyzed in the formation of two consecutive, irreversible first order reactions. The influence of temperature and solvent and stirring rate on the kinetic parameters (k1, k2, Rm max, tmax, Jd max, Ja max) have also been investigated. The membrane entrance rate, k1, and the membrane exit rate, k2, constants were increased with temperature and stirring rate. The membrane entrance and exit rate constants depend on the solvent type and are found to be in the order CH2Cl2>CHCl3>CCl4. For the maximum membrane exit flux, Ja max, the activation energy was found from the slope of the linear Arrhenius relationship to be 7.06 kcal/mol, which indicates that the process is controlled by species diffusion.
