摘　　要：研究了泡塑吸附Au、T1和Ta、RE络离子定量特性与动力学特性。还研究了Au在泡塑吸附中的均相分布特性。The adsorption character of metal ions with polyurethane foam has been studied. The test showed that polyfoam can absorb the complex aninos of Au, T1, Sb and Ta quantitatively from selected solution and kinetic character of absorbing Au, T1, Ta and REE was studied with polyfoam. The adsorption speed of polyfoam is dependent on condition of medium, complexs property and stability constant, diffusion speed of metal ions and cations radius to a large extend. The character of uniform distribution for adsorption of gold on polyfoam has been discussed too.
