羧化多壁碳纳米管/海藻酸钙水凝胶过滤膜对染料的截留性能
Dye retention properties of CMWCNT/CaAlg hydrogel filtration membrane
摘要
Abstract
In order to develop anti-fouling composite hydrogel nano-filtration membrane for dye desalination,carboxyl mul-ti-walled carbon nanotubes/calcium alginate(CMWCNT/CA)composite hydrogel filtration membrane was pre-pared using CaCl2solution as the cross-linker without pore-forming agent.The morphology of membranes were characterized by scanning electron microscope(SEM)and transmission electron microscope(TEM)respectively. The mechanical behavior of the membrane,anti-fouling property and the flux and rejection of dye salt solution were also investigated.Results revealed that the composite membrane had good mechanical properties and anti-fouling performance.The separation data revealed that the composite membrane containing 1% CMWCNT con-tent in NaAlg presented highest performance in terms of the rejections to Brilliant blue G250(Mw=854.02)be-ing 100%.And all the CMWCNT/CaAlg composite membranes almost had no rejection to NaCl.关键词
