用两相分配法测定了25±1℃条件下,反式N_(510)在煤油/水(pH=4.0)体系中的二聚常数 K_2和两相分配系数 Kd,用 CBVP—A_3型界面张力仪测定了反式N_(510)在煤油/水(1MNaCl+1MHCl)体系中的界面吸附特性参数,根据实验结果和 N_(510)单体及二聚体的分子结构推测,在液—液界面上吸附的是单体分子。
The bipolar constant K_2 and the two-phase partition coefficient Kd of trans-N 510 in kerosene / water (pH = 4.0) system were measured by two-phase partitioning method at 25 ± 1 ℃. The interfacial adsorption properties of trans-N 510 in a kerosene / water (1 M NaCl + 1M HCl) system were determined. Based on the experimental results and the molecular structure of N 510 monomers and dimers, Adsorbed on the monomer molecules.
