Zr-based metal-organic frameworks(MOFs)have been developed in recent years to treat heavy metals,*** chromium Cr^(6+)pollution,which damages the surrounding ecosystem and threaten human *** kind of MOF is stable and convenient to prepare,but has the disadvantage of low adsorption capacity,limiting its wide *** this end,a novel formic acid and amino modified MOFs were prepared,referred to as Form-UiO-66-NH_(2).Due to the modification of formic acid,its specific surface area,pore size,and crystal size were effectively expanded,and the adsorption capacity of Cr6+was significantly *** optimal conditions,Form-UiO-66-NH_(2) exhibited an excellent adsorption capacity(338.98 mg/g),∼10 times higher than that reported for unmodified Zr-based MOFs and most other *** in-depth study on the photoelectronic properties and pH confirmed that the adsorption mechanism of Form-UiO-66-NH2 to Cr^(6+)was electrostatic *** modification,the improvement of Cr^(6+)adsorption capacity by Form-UiO-66-NH_(2) was attributed to the expansion of its specific surface area and the increase in its surface *** present study revealed an important finding that Form-UiO-66-NH_(2) elucidated selective adsorption to Cr^(6+)in mixed wastewater containing toxic heavymetal ions and common nonmetallic water quality *** research provided a new acid and amino functionalization perspective for improving the adsorption capacity of Zr-based MOF adsorbents while simultaneously demonstrating their pertinence to target contaminant adsorption.
