| 摘 要： | 先用草酸处理水样中的镉离子,生成的Cd(C2O4)2]2-络阴离子通过强碱性阴离子交换树脂分离富集,最后用火焰原子吸收分光光度法测定了水样中的痕量镉。该法简便,选择性好,富集倍数高,应用于实际水样的检测,回收率为98%~102%,结果令人满意。

| Abstract: | This text has discussed the separation and collection of the trace cadmium by strong alkaline anion resin .Under the condition of oxalic acid , the cadmium anion is changed to complex anion , which is exchanged and collected through anion resin, and detected by AAS finally. This law has the advantages of convenient, good selectivity and collection.and it is applied to the measuring of the real water sample, the rate of recovery is 98%-102%, the result is satisfactory. |
