Abstract
In this article, calix[4]arene dinitrile‐oligomer (1) carrier was used as a carrier to transport Hg2+ ions from an aqueous solution into an aqueous receiving solution. The kinetic parameters (k1, k2, Rm max, tmax, Jd max, Ja max) were investigated with a temperature influence, solvent, and stirring rate, and analyzed in the formation of two consecutive, irreversible first order reactions. The membrane entrance rate, k1, and the membrane exit rate, k2, constants were increased with the temperature and stirring rate, and found to be dependent on the solvent type in order to 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 4.78 kcal/mol, which indicates that the process is controlled by species diffusion.
