摘　　要：在25±1℃下考察了N_(1923)(或TPHPO)-CHCl_3/HCl(或HCl-AuCl_4)和N_(1923)-TPhPO-CHCl_3/HCl(或HCl-AuCl_4^-)等6个体系的界面吸附特性,得到了各体系C_(min)、Γ_∞、A_1等界面吸附特性参数。结果表明,N_(1923)的界面活性明显强于TPhPO.当N_(1923)-TPhPO共存时的Γ_∞值较之N_(1923)或TPhPO单独存在时均有增加,可用于解释萃取动力学行为。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,N1913-TPhPO-CHCl3/HCl-AuCl4- were performed at 25℃;Cmin, Ta A1, the interfacial activity parameters of N1913and 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 mecba-nism.
