Study of hexavalent chromium ion adsorption on nano-porous anodic aluminum oxide

A CO2-gated anodic aluminum oxide based nanocomposite membrane for de-emulsification

“…13 Such porous membranes feature a high surface area, exceptional thermo-, chemical-and mechanical-resistance as well as excellent biocompatibility. 14 Therefore, the AAO membrane has been exclusively used as a filtration membrane in diverse fields of molecule separation such as amino acids, 15 nucleic acids, 16 proteins, 17 and others, 18 or water purification of various contaminated sources, e.g., dyes, 19 oil fouling, 20 heavy metal ions, 21 or desalination, 22 and so on. For example, Song et al prepared a polyrhodanine grafted AAO membrane via vapor deposition polymerization and the polyrhodanine-AAO composites obtained were utilized for the selective removal of Hg(II), Ag(I) and Pb(II) ions from contaminated water.…”
