摘要：

Two anion exchange resins - strongly basic Amberlyst A 29 and weakly basic Amberlyst A 21 - were applied to the adsorption of palladium(II) Complexes from HCl-NaCl Solutions over a range of acid concentrations (0.1-2.0 M) in 1.0 and 2.0 M NaCl using static and dynamic methods. The breakthrough curves of Pd(II) were used to calculate the ion exchange capacity, weight and bed distribution coefficients. Kinetic studies applied the Legergren's equation, the pseudo-second order and the inter-particle diffusion kinetic models to calculate kinetic parameters. it was observed that Amberlyst A 21 is more promising for adsorbing palladium(II) chloro-complexes from acidic chloride solutions than Amberlyst A 29. Furthermore. the type 1, pseudosecond order linear kinetic model has the highest correlation coefficient and gives the best fit between the experimental and predicted data.
