报道了一种合成功能介孔材料的新策略，用于高效去除铯。具体而言，以巯基修饰的SBA-15与五氰（4-乙烯基吡啶）高铁酸盐配合物为原料，通过光引发硫烯反应制备了普鲁士蓝衍生物修饰的SBA-15 （SBA-15@FC）。考察了普鲁士蓝衍生物的质量百分比、pH、吸附剂剂量、共存离子和初始浓度对铯离子吸附的影响。吸附动力学符合准二阶模型，在2h内达到平衡，吸附量约为13.90mg Csg(-1)，表明SBA-15@FC是一种有前途的有效去除水中铯的吸附剂。
A novel strategy to synthesize a functional mesoporous material for efficient removal of cesium is reported. Specifically, Prussian blue derivate-modified SBA-15 (SBA-15@FC) was prepared by photoinitiated thiol-ene reaction between thiol-modified SBA-15 and pentacyano(4-vinyl pyridine)ferrate complex. The effects of weight percentage of the Prussian blue derivate, pH, adsorbent dose, co-existing ions, and initial concentration were evaluated on the adsorption of cesium ions. The adsorption kinetically follows a pseudo-second-order model and reaches equilibrium within 2h with a high adsorption capacity of about 13.90mg Csg(-1), which indicates that SBA-15@FC is a promising adsorbent to effectively remove cesium from aqueous solutions.
