| 摘 要： | 为测量含氚废旧泵油的氚浓度,研究了表面活性剂十二烷基甜菜碱(BS-12)和脂肪醇聚氧乙烯醚(FEO)复配的表面化学性质和热力学性质,通过复配体系乳化泵油,并与液闪液形成分散体系达到测氚目的。结果表明,复配胶束浓度小于10-4 mol/L、BS-12与FEO复配体积比为6∶4、泵油测量体积小于0.012mL、NaCl浓度为0.1mol/L时具有稳定的测量结果。

| Abstract: | In order to determine tritium in tritiated waste pump oil,surface chemical properties and thermodynamic functions of BS-12/FEO/H2O system were studied.Mixed system was obtained when oil and scintillation liquid added in it.The results show that when surfactant concentration is less than 10-4 mol/L,V(BS-12):V(FEO) is 6:4,oil volume added to 5 mL of Ultima Gold LLT cocktail is less than 0.012 mL,NaCl concentration is 0.1 mol/L,quite stable liquid scintillation counting rate can be obtained. |
