- Abstract:
- A new type high desahing nanofiltration membrane was fabricated by use of interfacial polymerization techniques onto aporous support polyether sulfone(PES)uhrafihration membrane．The separation factorof membrane for NaCI and xylenol orange(XO)in the XO／NaCl／water system was used as the object of studyand the uniform design was applied to the preparation process．The experimental data were treated by SPSSsoftware，and the regression equation was established．And the calculation results of the regression equation a—gree well with the experimental data．The separation factor can reach 1 6 at the optimal condition which wasobtained by calculation with the regression equation and further experiment as follows：polyamine flocculants0．68％(wt)；2，5一diaminobenzene sulfonic0．4％(wt)in inorganic phase；trimesoyl chloride 0．4％(wt)inorganic phase；interfacial polymerization(IP)time 2．5 min．Then，the separation factors were investigated forXO with the four salts．The results show that the optimized composite membrane has the good effect for separating XO with salts．
