STUDIES ON HETERO ATOMIC POLYMERIC CROWN ETHERS Ⅰ. SYNTHESES AND CHARACTERISTICS OF RESINS OF ETHYLENE GLYCOL BISGLYCIDYL ETHER CROSSLINKED BY POLYAMINE

以乙二醇双缩水甘油醚（ＥＧＢＥ）为原料，多乙烯多胺为交联剂，合成了一系列氮杂聚合物冠醚树脂，并研究了其在不同极性的溶剂中的溶胀性能和对几种过渡金属离子的静态吸附性能。结果表明，该类树脂在极性溶剂中具有良好的溶胀性能，其在水中的膨胀系数可达３．６６，其对Ｃｕ（Ⅱ）、Ｎｉ（Ⅱ）的吸附容量可分别达到１．５１和１．３８ｍｍｏｌ／ｇ干树脂。

Using ethylene glycol bisglycidyl ether (EGBE) as material and polyethylenepolyamine as crosslinking agent, a series of polymeric aza crown ethers were synthesized. Their swelling properties at different conditions such as polarity of solvent, pH value, temperature, and their static adsorption properties for several transition metallic ions were investigated. The experimental results show that the stronger the polarity of solvent is, the more the swelling coefficient ( K ), the best pH value is about 6￣7; these resins have better adsorption properties for Cu 2+ than 330 # resin (made in China), the adsorption for Cu 2+ and Ni 2+ are 1.51 and 1.38 mmol/g dry resin respectively. The above mentioned resins will have wide use in treating industral waste water which contains heavy mettalic ions.
