| The poly(acrylamide co-acrylic acid) - sodium alginate hydrogels for heavy metal removal were prepared by electron beam irradiation using the 5.5 MeV electron beam accelerator, ALID-7. The irradiation dose was between 1.9 kGy and 9.5 kGy and the influence on the swelling properties was investigated. The hydrogels were tested for heavy metal removal in uptake experiments made on aqueous solutions of 635 and 1270 ppm Cu2+, respectively. The absorption of Cu2+ ions was over 400 mg/g and 120 mg/g, respectively. |
