合成了一种二维窗口型膦酸锆材料β-丙氨酸-N,N双亚甲基膦酸锆(ZrNCP),采用X射线衍射仪、扫描电镜、透射电镜分析了合成产物的相组成和微观结构；利用N2吸脱附试验装置测定了合成产物对不同金属离子的吸附性能,考察了浓度、温度及pH对其吸附性能的影响.结果表明,合成产物内部存在大量分布均匀的微介孔,材料微观形貌为规整片状.随着金属离子半径的增大,ZrNCP对各种金属离子的平衡吸附量(mmol/g)呈逐渐减小趋势.%Two dimensional window type zirconium phosphonate, β-alanine-N,N-dimethylphos-phonate (ZrNCP), was prepared. The phase composition and microstructure of as-synthesized product were analyzed by means of X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Moreover, a nitrogen adsorption-desorption test rig was performed to evaluate the adsorption performance of as-synthesized ZrNCP for several metal ions; and the effects of concentration, temperature and pH value on the adsorption performance of as-synthesized product were investigated. Results show that there is a large amount of uniformly distributed mesopores inside the as-synthesized product, and target product has regular plate-like morphology. Moreover, the adsorption capacities (mmol/g) of ZrNCP for various metal ions tend to gradually decline with increasing radius of the metal ions.
