| 中文摘要 |
| 研究伯胺N1923萃淋树脂在萃取剂N1923成盐和不成盐时不同条件下吸附汞的反应机理,通过等摩尔系列法、斜率法、饱和容量法等确定吸萃物在成盐和非成盐时的组成分别为:(RNH3+)2HgCl42-和(RNH)2HgCl2。并通过红外光谱和核磁共振光谱分析吸萃过程中的不同机理:成盐时为离子交换机理,非成盐时为配位机理。 |
| 英文摘要 |
| The adsorption mechanisms of mercury (Ⅱ) with prime amine (N1923) levextrel resin were studied when it doesn't form salt or it is in salt forming condition. The adsorption compounds have been determined and the different mechanisms have been analysed from the results obtained by using constant mole method, slope method, saturated capacity method, IR and NMR spectra, and also discussed the different mechanism in low or high concentration of [HCl] on the theroy. |
