The Adsorption of Zinc(II) on Anion-exchange Resins. II. Stoichiometry, Thermodynamics, Loading Studies, Dowex-2 Adsorption and Factors Influencing the Rate of the Adsorption Process

摘要: The adsorption of macroscopic amounts zinc(II) on Dowex 1-XB chloride has been studied at room temperature; the content resin doubles with equivalent species. tracer 1-X8 from LiCl and HC1 solutions 0.25 49 deg studied, results indicate presence a secondary process resulting in apparent high concentrations. Loading studies that capacity l for chloro- complex ions is same as ion, thus rendering unlikely supposition other than ion exchange functional groups. 2 HCl solutions, while somewhat less, substantially 1. influence mesh amount, concentration various constituentc; solution phase, solvent composition rate desorption processes together radiozinc(II) between phases.
