Abstract
The uptake behavior of Am3+ was investigated by using alginic acid and algi nate polymer gels. The affinity of radioactive nuclides for carboxyl groups in gel matrices increased in the order of Na+ < Cs+ < Co2+ < Pd2+, Sr2+, F e3+ < Eu3+, Am3+. Among alginate gels, calcium alginate exhibited relativel y higher uptake rate and distribution coefficient of Am3+. The column packe d with calcium alginate beads was effective for the removal of trace amount s of Am3+ from acidic nitrate solutions.
