Aiming at the separation of Pd(II) along with MA(III) from high-level liquid waste, a porous silica based adsorbent isoBu-BTP/SiO2-P was prepared. The adsorption properties of isoBu-BTP/SiO2-P toward Pd(II) were investigated. It was found that with the increase of HNO3 concentration, Pd(II) adsorption ability increased initially as HNO3 concentration increased until 1 M, then remained unchanged as HNO3 concentration further increased. The adsorption kinetics and isotherm of Pd(II) onto isoBu-BTP/SiO2-P fit well with the pseudo-second-order rate law and Langmuir adsorption model, respectively. The adsorption thermodynamic parameters revealed that the adsorption process was spontaneous and endothermic. A hot test utilizing isoBu-BTP/SiO2-P packed column was conducted and the simultaneous separation of Pd(II) and MA(III) was achieved from solution by using 0.01 M HNO3-0.1 M TU and 0.01 M HNO3-0.01 M DTPA as eluents, respectively. The Pd(II) with isoBu-BTP/SiO2-P complex was illustrated to be 1:1 type by HRMS, while 1:3 Eu(III) to isoBu-BTP complex was found by single-crystal X-ray diffraction.

iso Bu-BTP / SiO 2 -P吸附剂从高放废液中分离钯和次Act系元素
旨在从高放废液中分离出Pd（II）和MA（III），制备了多孔二氧化硅基吸附剂iso Bu-BTP / SiO 2 -P。研究了异Bu-BTP / SiO 2 -P对Pd（II）的吸附性能。发现随着HNO 3浓度的增加，Pd（II）的吸附能力最初随着HNO 3浓度的增加而增加，直至1 M，然后随着HNO 3浓度的进一步增加而保持不变。Pd（II）在iso Bu-BTP / SiO 2上的吸附动力学和等温线-P分别与拟二阶速率定律和Langmuir吸附模型很好地拟合。吸附热力学参数表明吸附过程是自发的且吸热的。使用iso Bu-BTP / SiO 2 -P填充柱进行热测试，并使用0.01 M HNO 3 -0.1 M TU和0.01 M HNO 3从溶液中同时分离Pd（II）和MA（III）-0.01 M DTPA分别作为洗脱液。用HRMS证实具有iso Bu-BTP / SiO 2 -P配合物的Pd（II）为1：1类型，而通过单晶X射线发现与iso Bu-BTP配合物为1：3的Eu（III）。衍射。
