  • Title: The fast removal of low concentration of cadmium(II) from aqueous media by chelating polymers with salicylaldehyde units.
    Author: Amoyaw PA, Williams M, Bu XR.
    Journal: J Hazard Mater; 2009 Oct 15; 170(1):22-6. PubMed ID: 19501464.
    Abstract:
    Poly[4-(4-vinylbenzyloxy)-2-hydrobenzaldehyde], PVBH, a salicylaldehyde chelating functional group-based polymer has been found to be capable of the removal of low concentration of cadmium metal ion in ppb level from aqueous media. The adsorption fits best with the Langmuir model, indicating the monolayer coverage of the metal ion on the surface of chelating polymer. The R(L) values have indicated the favorable adsorption in the range of all the ppb concentrations studied. The kinetic study has revealed a very fast adsorption process with the rate following the pseudo-second-order.
