Abstract：

The self-made positively charged guanidine nanofiltration membrane was used for dye desalination. Results showed that the retention rate of congo red and reactive blue 19 with higher molecular weight was higher than 95% and 90%, respectively, followed by methyl orange with lower molecular weight. The retention of NaCl and Na2SO4 by the membrane is low, which indicated that the membrane can effectively separate dye and salt. The concentration of dyes and salts has an important effect on the separation performance of the membrane. With the increase of dye concentration, the membrane flux decreased, while the retention of congo red and NaCl changed little, the retention of methyl orange, reactive blue 19 and Na2SO4 increased slightly. The increase of inorganic salt concentration had little effect on the membrane flux, but led to the decrease of the rejections of dye and salt. For three simulated pollution systems, including congo red-NaCl, methyl orange-NaCl and reactive Blue 19-NaCl, after four pollution-cleaning cycles, all of the membrane showed relatively high fluxes, which demonstrated that the membrane had satisfactory antifouling performance. Furthermore, the membrane maintained good stability in the long-term filtration operation of methyl orange-NaCl system for 24 h.
