配合物与载体相互作用的研究

本文研究了配合物与载体的相互作用。载体浸渍于配合物的溶液时,两者间的相互作用可分成四类:(1)无明显的化学作用;(2)配合物与载体通过桥联的配体作用;(3)载体阳离子与解离的配体作用;(4)载体促进金属水合离子的水解。

A Study on the Interactions Between Coordination Compounds and Supports

In this study the viewpoint is taken that the supported complexes react with active groups on the surface of support to form new entities which may be called surface complexes. Various interactions between the support and the solution of impregnation have been found, and these interactions may be divided into four classes, (1) those that there is no noticeable chemical interaction between the coordination compound and the support, except the physical adsorption; (2) those that the metal ion of the complex is anchored on the surface through the surface group as a ligand forming a surface complex, or the support provides the central ion for the formation of a surface polynuclear complex through the bridging ligand of the complex; (3) those that the surface of the support provides the central ion for ligands dissociated from the complex or for the solvent molecules; (4) those that the metal hydroxide might be formed, when the acidity of the cation of the support is weaker than that of the metal ion of the complex in aqueous solution.
