纤维素基磁性聚偕胺肟树脂的研究:—PdCl2在树脂上的吸附动力学
-
摘要: PdCl2在碱式纤维素基磁性聚偕胺肟树脂上的吸附行为与H2PdCl4不同,主要表现在高的超当量吸附。动力学研究表明,H2PdCl4在碱中和过程中逐步转变为Na2PdCl4、PdCl2、和[Pd(OH)2Cl2]2,它们被树脂吸附时首先形成AO-Pd2和AO2-Pd3络合物,随后被还原为单质钯,汇聚成微粒吸着在树脂表面。Abstract: The adsorption behaviors of palladium dichloride adsorbed by alkaline cellulose-based magnetic polyamidoxime adsorbent(BMAO) differ from that of chloropalladic acid. An important basis is the high value of super-equivalent adsorption. Investigation of ads
