| 摘要: |
| 本文利用含有三正辛胺为载体的氯仿大块液膜,研究了溴离子迁移的规律;考察了溴离子浓度、载体浓度,接收相组成等因素对溴离子在液膜中迁移作用的影响。利用接收相的酸碱反应实现了溴离子的活性迁移。根据软硬酸碱理论,提出并实验证实了选取适当的载体可以提高溴离子迁移的选择性。本研究可作为液膜法海水提溴的基础性研究。 |

| MIGRATION BEHAVIOUR OF BROMINE ION IN LIQUID MEMBRANE |
|
|
| Abstract: |
| In this paper the migration rules of bromine ion is studied by using the choloroform bulk liquid membrane containing TnOA as carrier. The migration behaviour of bromine ion is influenced by the concentrations of bromine ion, carrier and the receive phase etc. The active migration of bromine ion is realizaed by virtue of acid basic reaction in receive phase. according to the soft hard acid-basic (SHAB) theory, the employment of a suitable carrier can improve the selectivity of bromine ion. |
