一、项目介绍以乙二胺、二乙烯三胺、三乙烯四胺和四乙烯五胺等脂肪多胺为原料合成含有脂肪多胺环状结构的树脂,依靠脂肪多胺环结构和金属离子的配位可吸附金属离子。采用不同的脂肪多胺为原料可以得到环状结构大小不同的树脂,对不同的贵金属或者过渡金属离子,如金、银、汞、铬和铜等,进行高选择性的吸附。该吸附树脂吸附贵金属速度快,吸附率高,吸附容量大,选择性高,在不同p H值下,尤其是碱性介 I. Introduction to the project Ethylenediamine, diethylenetriamine, triethylenetetramine and tetraethylenepentamine and other fatty polyamines as raw material synthesis of fatty polyamine ring structure of the resin, relying on fatty polyamine ring structure and metal ions Coordination can adsorb metal ions. Using different fatty polyamines as raw materials, resins with different ring structures can be obtained, and highly selective adsorption is performed on different precious metals or transition metal ions such as gold, silver, mercury, chromium and copper. The adsorption resin adsorbed noble metal fast adsorption rate, adsorption capacity, high selectivity, at different p H value, especially alkaline medium
