Firstly , allocation coefficient , diffusion coefficient and reactive extraction equilibrium constant were determined , as well the operation factors affecting these parameters ( 1 )测定包括分配系数、水相扩散系数和表观反应萃取平衡常数等基础参数,并分析了各操作条件对它们的影响。
The results showed that kp value increased with the increase of the initial concentration and ph value of the feed phase . the determined diffusion coefficient showed good agreement with the value that were calculated by the experiential equation given by castillo r . . reactive extraction equilibrium constant kr increased with the increase of the initial concentration of the feed phase and the carrier concentration , while kr value increased slowly in the high initial concentration of the feed phase 分配系数的研究结果表明,分配系数kp随着料液苯酚浓度增大而增大,随料液ph值增大而升高;采用多孔板法测定水相中苯酚的扩散系数,并将测定值与经验公式估算值进行对比,结果表明,测定结果是可靠的;表观反应萃取平衡常数kr随着载体浓度升高而增大,随着料液浓度的增加而增大,而在浓度较大时, kr增大趋势变缓。
