The separation of MNGM-PET and PET membrane for Li+, Na+, K+, Rb+, Cs+ and Cl-. ∆pH = 1.5, t = 25 °C, Cions = 0.1 mol/L. (A) (B) (C) and (D) are the MNGM-PET filters. (E) (F) (G) and (H) are the PET filter. The Y-axis is the ion concentration that crossed the membrane. (I,J) Cl- filtration across the MNGM and PET membrane. (∆pH = 1.5, t = 25 oC, Cions = 0.1 mol/L). (I) is Cl- analysis using ion chromatography. The peak of NO3- can only be observed in the sample of mgNM-PET and PET, the Cl- could not be found in all samples. (J) is Cl- concentration analysis with AgNO3. 1 was the control group, 2 was the MNGM-PET 3-h after filtration, 3 was the PET membrane 3-h after filtration, AgCl precipitations could not be observed in all samples.
