Preparation of SAMS-CMC-CS Bipolar Membrane and Its Application in Electro-generating FeO~(2-)_4

摘要

The preparation of SAMS-CMC-CS bipolar membrane grafted onto CMC by SAMS was reported.The cross-section view of SAMS-CMC-CS BM were studied by SEM.FT-IR spectrum indicated that SAMS-CMC-CS BM contained-SO_3~- ,-COO~-and-N=CHR functional groups.Compared with CMC-CS BM,SAMS-CMC-CS BM appears to have better mechanical strength and chemical stability in alkali solution at[OH~_]>=9.5 mol/L,with a swelling of 55%.The electrochemical properties of SAMS- CMC-CS BM were also studied.SAMS-CS-CMC BM not only e?ectively prevented FeO_4~(2-) from diffusing into the cathode chamber,but also played an important role in the supply of OH~- consumed during the electro-generated FeO_4~(2-) Process.
