| STUDIES ON THE ESTERFACIAL PROPERTIES OF PRIMARY AMINE (N1923) AND TRIPHENYLPHOSPHINE OXIDE(TPhPO) |

| 摘要: 在25±1℃下考察了N1923(或TPHPO)-CHCl3/HCl(或HCl-AuCl4)和N1923-TPhPO-CHCl3/HCl(或HCl-AuCl4-)等6个体系的界面吸附特性,得到了各体系Cmin、Γ∞、A1等界面吸附特性参数。结果表明,N1923的界面活性明显强于TPhPO.当N1923-TPhPO共存时的Γ∞值较之N1923或TPhPO单独存在时均有增加,可用于解释萃取动力学行为。 |

| Abstract: Gibb's absorption curves for the systems of N1923-CHCl3/ HC1,N1923-CHC13 / HCl-AuCl4-,TPhPO-CHCl3 / HCl.TPhPO-CHCl3 / HCl-AuCl4-,N1923-T PhPO-CHCl3/HCl,N1923-TPhPO-CHCl3/HCl-AuCl4- were performed at 25℃;Cmin, Ta A1, the interfacial activity parameters of N1923and TPhPO were also obtained. The experimental results show that interfacial activity of N1923 is greater than that of TPhPO; when N1923 and TPhPO coexist in the same system, the value of is greater than that in the system when N1923 or TPhPO is present alone. These results could be used to explain the extraction mecbanism. |
