Adsorption and separation performances of a microporous silica-based (DAMIA-EH + TOA)/SiO2-P adsorbent towards Pd(II) were systematically investigated under the effect of contact time, temperature, concentration of nitric acid, chromatography etc. in a simulated high-level liquid waste containing 14 kinds of representative co-existing metal ions. Successful recovery of around 97.95% Pd(II) was achieved under the elution with 0.01 M Tu (pH = 2) solution in column experiment.

钯（II）在二氧化硅基杂化供体吸附剂上从模拟高放废液中的吸附分离行为

系统研究了微孔二氧化硅基（DAMIA-EH + TOA）/SiO2-P 吸附剂在接触时间、温度、硝酸浓度、色谱等影响下对 Pd(II) 的吸附和分离性能。含有14种代表性共存金属离子的高放废液。在柱实验中，在用 0.01 M Tu (pH = 2) 溶液洗脱下，成功回收了约 97.95% 的 Pd(II)。
