通过间歇实验和吸附动力学研究了As(III, V)的去除性能。在pH为9.2 0.1时，UiO-66对As(III)和As(V)的去除率分别为205.0和68.21 mg/g。通过吉布斯自由能计算和Dubinin-Radushkevich (D-R)等温线模型验证了As去除过程是放热的，为化学吸附反应。固定床反应器去除实验表明，As(III)和As(V)的有效处理体积分别达到2270和1775 BVs，直至达到最严格的As调节水平10 lg/L(初始As浓度为100 lg/L)。FTIR和XPS研究表明，锆金属-有机框架的ZrAO键在吸附As中起重要作用。XANES研究表明，As吸附在UiO-66上，氧化态没有变化。更有趣的是，EXAFS光谱显示，在UiO-66的六核Zr簇上，As(V)和As(III)主要形成双齿双核配合物。金属锆-有机骨架材料具有无毒、稳定性高、吸附砷量大、成本低、易得等优点。

The removal performance of As (III, V) was studied through intermittent experiments and adsorption kinetics. At a pH of 9.2 0.1, the removal rates of As (III) and As (V) by UiO-66 were 205.0 and 68.21 mg/g, respectively. The Gibbs free energy calculation and Dubinin Radushkevich (D-R) isotherm model confirmed that the As removal process is exothermic and a chemical adsorption reaction. The fixed bed reactor removal experiment showed that the effective treatment volumes of As (III) and As (V) reached 2270 and 1775 BVs, respectively, until reaching the strictest As regulation level of 10 lg/L (initial As concentration of 100 lg/L). FTIR and XPS studies have shown that the ZrAO bond in the zirconium metal organic framework plays an important role in the adsorption of As. XANES research shows that As adsorbs on UiO-66 without any change in oxidation state. More interestingly, EXAFS spectroscopy shows that on the hexagonal Zr cluster of UiO-66, As (V) and As (III) mainly form bidentate binuclear complexes. Metal zirconium organic framework materials have the advantages of non toxicity, high stability, large arsenic adsorption capacity, low cost, and easy availability.
