中文摘要:
      用静态法研究了8-羟基喹哪啶螯合树脂在酸性溶液中吸附和解吸Pd(II)的性能,分析了吸附等温线和吸附动力学过程。结果表明,在0.6 mol/L HCl的介质中,树脂对Pd(II)的饱和吸附量为99.46 mg/g,吸附率为94.7%,解吸率达到95.6%;吸附过程符合Langmuir和Freundlich等温吸附模型,准二级动力学Lagergren方程更适合描述此吸附过程。
英文摘要:
      The property of 8-hydroxyquinoline chelate resin (PS-HQD) for adsorption and desorption Pd(II) from solution were studied with static adsorption, andthe adsorption isotherm and kinetics were analyzed. The results showed that saturated adsorption capacity was 99.46 mg/g, adsorption and desorbtion rate of PS-HQD could reach 94.7% and 95.6% in 0.6 mol/L HCl solution, respectively. The equilibrium adsorption followed to both Langmuir and Freundlich isotherms models, and the Lgergren pseudo-second order kinetic model was more suitable for describing the adsorption process.
