摘要

研究了γ 辐射三烷基氧化膦（TRPO）的乳化性能。实验表明，萃取水相酸度的增加，有利于去乳化作用。γ 辐射对30%TRPO-煤油一硝酸体系的乳化作用有显著影响，不同厂家生产的TRPO具有不同的乳化性能。γ 辐照的磷酸三丁酯（TBP）-煤油-硝酸体系较TRPO-煤油-HNO,3,体系分相和去乳化速度较快。但当用5%Na,2,CO,3,溶液洗涤上述两个体系时，TBP-煤油体系有机相去乳化速度较慢，其平衡水相有乳化现象，而TRPO-煤油体系虽分相慢，但分相后有机相的去乳化速度较快，其平衡水相无乳化现象。

Abstract

Emulsion characteristics and demulsification performance of trialkylphosphine oxide(TRPO), which is a useful extractant for treatment of high active waste, were studied by spectrometric method. Results showed that demulsification of organic phase equalized with nitrate acid became faster than with pure water. The emulsion characteristics were compared with TRPO of various sources. The effect of γ-irradiation was remarkable for emulsion formation of TRPO. The emulsion of irradiated TBP(Tributyl phosphate) and TRPO were compared. Demulsification of TRPO was slower than irradiated TBP. When using a 5%Na,2,CO,3, as solvent cleanup reagent, the phase separation of irradiated TBP was faster than irradiated TRPO, but demulsification of aqueous phase was slower for irradiated TBP.
