摘　　要：在反萃取过程中出现有机相夹带水相现象,容易引起有机相再生后的废液中铀含量升高,造成环境污染。试验筛选出改性纤维和棉纱亲水吸湿功能材料,对有机相中水分的分析方法进行了比选,并开展了2种亲水吸湿性材料对30%TBP+磺化煤油的反萃取过程的除水试验。结果表明:对于30%TBP+磺化煤油的反萃取体系,卡尔费休库仑法是最适宜的水分分析法;改性纤维和棉纱均可实现反萃取过程中有机相夹带水的100%去除。In the re-extraction process,the water phase of entrainment in organic phase can be formed,which can lead to high uranium content in the waste liquid after the regeneration organic phase and environmental pollution.Two suitable hydrophilic function materials,named as modified fibers and cotton yarn were selected by experiment.The detection method of moisture in organic phase was compared and chosen.The dewatering experiment was carried out on the re-extraction process of 30% TBP+sulfonated kerosene with two hydrophilic materials.The results show that for the re-extraction system of 30% TBP+kerosene,Karl fischer coulomb method is the most suitable for water content analysis,and the hydrophile function fibre and cotton yarn can make 100% removal of organic phase entrainment in the process of re-extraction.
