摘要
合成了五种分子内分别含有－OC2H4NHC2H4OH、－OC2H4N（C2H4OH）2和－OC2H4NH（C2H4NH）nH（n＝1，2，3）功能基的螯合树脂．研究了它们对Ag（Ⅰ）的静态吸附性能．结果表明，吸附具有典型的Langmuir和Freundlich特征：液膜扩散是吸附的主控步骤；其对Ag（Ⅰ）的平衡吸附量可分别达0．773，0．466，0．958，1．398和1．947mmol·g－1；吸附过程伴有缓慢的氧化还原作用．
Five novel chelating resins, with ether bond and such functional groups as -NHC2H4OH, -N(C2H4OH)2, and - NH(C2H4NH)nH (n = 1, 2, 3), were separately synthesized,and their Static adsorption properties for Ag(l) were investigated. All adsorption processes have typical characteristics of Langmuir and Freundlich, The major controlled step of adsorption rate was liquid film diffusion; The adsorption capacities were 0.773, 0.466, 0.958, 1.398 and 1.947 mmol·g-1, respectively,There was slowly oxidation - reduction action in the adsorption process.
