By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Phenols are presented in a new report. According to news reporting originating in Jinan, People's Republic of China, by NewsRx journalists, research stated, "Magnetic cyclodextrin-chitosan/graphene oxide (CCGO) with high surface area was synthesized via a simple chemical bonding method. The characteristics results of FOR, SEM, TEM and XRD showed that CCGO was prepared."
The news reporters obtained a quote from the research from Shandong University, "The large saturation magnetization (22.35 emu/g) of the synthesized nanoparticles allows fast separation of the CCGO from liquid suspension. These composites could efficiently remove hydroquinone from simulated wastewater with a facile subsequent solid-liquid separation because of their large area, abundant hydroxyl and amino groups with handy operation, and hydrophobicity. The hydroquinone removal process was found to obey the Freundlich adsorption model and its kinetics followed pseudo-second-order rate equation. The hydroquinone removal mechanism of CCGO might be attributed to the electrostatic adsorption of hydroquinone in the form of negatively charged hydroquinone by positively charged chitosan, accompanying hydroquinone absorbed by cavities of the cyclodextrin, and forming hydrogen bonds between hydroquinone and the hydroxyl groups on the surface of CCGO. The used CCGO could be recovered with ethanol."
According to the news reporters, the research concluded: "This study provides a promising nanostructured adsorbent with easy separation property for heavy metal ions removal."
