What is Preparation of SAMS-CMC-CS bipolar membrane and its application in electro-generating FeO42− about?

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 effectively prevented FeO 2- 4 from diffusing into the cathode chamber, but also played an important role in the supply of OH -consumed during the electro-generated FeO 2- 4 process.
