摘　　要：用原子吸收分光光度计、X射线衍射等手段，研究了粘胶基活性炭纤维（VACF）对Pd2的吸附结果表明：活性炭纤维不但能吸附较多的Pd2，而且能与Pd2发生氧化还原反应，吸附了Pd2的活性碳纤维上出现金属或颗粒。In this paper, the basic adsorption characteristics of VACF (viscose-fiber-based activated carbon fiber) for Pd2+ were investigated by using Atomic Absorption Spectrometer, X-ray diffraction, and other analytic methods. The experimental results indicated that the VACF has better redox adsorption ability for Pd2+ during the adsorption process. It has been confirmed that Pd2+ adsorbed on VACF has been reduced into elemental Pd except in the case of adsorption in [Pd(NH3)4Cl2] solution. The adsorntion amount of VACF for Pd2+ depends upon not only the technical conditions of preparation of VACF, but also the form of Pd2+ in adsorption solution, which restricts the electrode potential of oxidants.
