英文摘要The silica/polymer-based isoHex-BTP adsorbent (isoHex-BTP/SiO2-P) was prepared for partitioning Am(III) and Cm(III) from HLLW. Batch adsorption results showed that isoHex-BTP/SiO2-P exhibited high affinity and selectivity for Am(III) and Pu(IV) over U(VI), Ln(III) and other typical fission products in 3 mol dm(-3) nitric acid. The effects of contact time, initial Dy(III) concentration and temperature on the adsorption of Dy(III) [as a simulated element of MA(III) and a representative element of Ln(III)] by isoHex-BTP/SiO2-P in 3 mol dm(-3) nitric acid were investigated. The adsorption of Dy(III) fitted well to the pseudo-second-order kinetic model and the Langmuir isotherm model. The adsorption thermodynamic parameters revealed that the adsorption was a spontaneous, endothermic and entropy-driving process.; The silica/polymer-based isoHex-BTP adsorbent (isoHex-BTP/SiO2-P) was prepared for partitioning Am(III) and Cm(III) from HLLW.
