| Popis: | A new metal chelating polymer has been synthesized using Amberlite XAD‐16 (AXAD‐16) polymer matrix, chemically modified using oxyacetone acetamide as the functional group. The resin was characterized by Fourier transform‐infra red (FT‐IR) studies, elemental analysis, and thermogravimetric analysis. The metal extractive efficiency of the functionalized resin matrix was examined and it was found that the synthesized resin showed high selectivity and preconcentrating ability toward trace heavy metal ions. Various physiochemical and kinetic factors operating on the quantitative metal ion extraction were studied and optimized. It was found that quantitative metal ion sorption was possible in the pH range of 5.0–7.0, 3.0–4.0, 5.0, and 6.0–7.0 for U(VI), Th(IV), Pb(II), and Cd(II), respectively. The developed resin showed faster exchange rates and a high metal exchange capacity value of 202, 185, 179, and 86 mg g−1 for U(VI), Th(IV), Pb(II), and Cd(II), respectively. The newly synthesized resin possesse... |
