AB  - The kinetics of as (III) removal was studied by batch experiment. At pH 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. Gibbs free energy calculation and Dubinin radushkevich (D-R) isotherm model verify that the as removal process is exothermic and is a chemical adsorption reaction. The removal experiment of fixed bed reactor shows that the effective treatment volumes of as (III) and as (V) reach 2270 and 1775 BVS respectively until they reach the strictest as regulation level of 10 LG / L (the initial as concentration is 100 LG / L). FTIR and XPS studies show that the zrao bond of zirconium metal organic framework plays an important role in the adsorption of as. XANES study showed that as was adsorbed on uio-66, and the oxidation state did not change. More interestingly, EXAFS spectra showed that as (V) and as (III) mainly formed bidentate binuclear complexes on the six nuclear Zr cluster of uio-66. Metal zirconium organic framework material has the advantages of non-toxic, high stability, large amount of arsenic adsorption, low cost and easy availability. Special adsorption of arsenic by metal organic framework zirconium: the data set of engineering exploration and mechanism discussion is obtained by experimental method. The data format is decimal (. XLS), and the amount of data is 5 groups, a total of 34500 experimental data.
