Selective Removal of Mercury(II) Using Hydrogels Prepared by Gamma Radiation

To selectively remove mercury(II), 2-hydroxyethyl methacrylate (HM) and methacrylate/acrylamide (HM/ACR) hydrogels were synthesized using radiation. These used in swelling, diffusion, binding studies. Swelling parameters for HM/ACR−Hg2+ system are higher than those of HM−Hg2+ systems. Binding Hg2+ has been observed to be C-type HM L-type HM/ACR hydrogels. calculated Freundlich, Langmuir Henry models. Effects concentration, radiation dose, ACR ratio, temperature, counter ions investigated. swelling increased with the incorporation acrylamide. absorbed only Hg2+, did not absorb heavy metal ions.
