| 中文摘要 | equilibrium distributions of cobalt(ii), nickel(ii), zinc(ii), cadmium(ii), and copper(ii) have been studied in the adsorption with extraction resin containing 1-hexyl-4-ethyloctyl isopropylphosphonic acid (heoppa) as an extractant from chloride medium. the distribution coefficients are determined as a function of ph. the data are analyzed both graphically and numerically. the extraction of the metal ions can be explained assuming the formation of metal complexes in the resin phase with a general composition ml2(hl)(q). the adsorbed species of the metal ions are proposed to be ml2 and the equilibrium constants are calculated. the efficiency of the resin in the separation of the metal ions is provided according to the separation factors values. the separation of zn from ni, cd, cu, co, and co from ni, cd, cu with the resin is determined to be available. furthermore, freundlich's isothermal adsorption equations and thermodynamic quantities, i.e., deltag, deltah, and deltas are determined. |
