Oxalic acid cross-linked sodium alginate and carboxymethyl chitosan hydrogel membrane for separation of dye/NaCl at high NaCl concentration
文献摘要：
Dye desalination is a challenge in the treatment of textile wastewater with high salt concentration.It is imperative to develop salt resistance membrane that is from sustainable materials to effectively treat dye/salt mixtures.And most polymer membrane materials are non-renewable petrochemical resources.In this paper,a green hydrogel membrane(CMCS-OA-NaAlg)was prepared by non-metallic ions of oxalic acid(OA)cross-linking of two natural macromolecules of sodium alginate(NaAlg)and carboxymethyl chitosan(CMCS).The membrane showed excellent anti-swelling at high salt concentration(swelling rate less than 8.0％in 10.0 wt％NaCl solution)and good anti-fouling performance.The membrane exhibited a rejection higher than 95.0％for dyes(bright blue,direct black,direct red,and Congo red)and lower than 7.0％for NaCl,which can achieve better dye/NaCl separation performance.This study provides a promising membrane material for high salt textile wastewater treatment only using water and carbohydrates as raw materials without any organic solvents.
