Formaldehyde 8 hydroxyquinoline sodium benzene sulfonate resorcinol copolymer described as chelating ion exchange resin was synthesized.
用8羟基喹啉、甲醛、间苯二酚及苯磺酸钠作原料合成了一种螯合树脂。
As the chelating resin in the electrode can exerts a concerted effect of ion exchange and coordination with copper, this method produces a high sensitivity and selectivity.
由于修饰在电极上的螯合树脂与铜离子在进行离子交换的同时发生螯合反应，故本法具有较好的选择性和较高的灵敏度。
