| 摘 要： | 采用气相EPICS(equilibrium partitioning in closed system)法研究了甲苯与非离子表面活性剂TritonX-100(TX100)溶液间气液平衡分配关系.研究表明,甲苯的表观亨利系数(Hc)随TX100浓度的增加而降低,TX100可明显地影响甲苯在气液相的分配行为,抑制甲苯挥发;当TX100的浓度低于其临界胶束浓度(CMC),浓度的增加对Hc影响不明显,抑制甲苯挥发能力相对较弱;浓度大于CMC,Hc随表面活性剂浓度的增加迅速降低.温度对Hc的影响显著,温度升高,相应Hc也随之增大.

| Abstract: | Effect of nonionic surfactant,Triton X-100 (TX100),on the relationship of the vapor-liquid partitioning of toluene was studied by equilibrium partitioning in closed system(EPICS).The results showed that the apparent Henry,s constant(Hc)reduced significantly with increasing TX100 concentrations and the vapor-liquid partition behavior of toluene changed obviously by increasing the aqueous concentration of TX100.Therefore,the volatilization was restrained.Hc changed slowly and the restraining ability of TX100 ... |
