| Abstract | Due to the relatively excellent chemical and hydrothermal stability as well as structural stability, UiO-type PCPs exhibit good adaptability in the humid and acid atmosphere. Considering that, we anchored this type of materials to study their structural properties and adsorption behavior. Concretely, we have synthesized UiOs with different pore diameters by employing different length organic ligand and prepared magnetic functional Fe3O4@UiOs by encapsulation. In this paper, we have studied the adsorption behavior of four UiO-type PCPs on AO7, and the optimum adsorption amount of UiO-67 on acid orange 7 achieving 250 mg/g. The adsorption mechanism was then discussed in detail by combining the porosity and the Zeta potential analysis. When the PCPs are mainly mesoporous, the adsorption manner fits physical adsorption, while microporous is in accordance with chemisorption. The adsorption capacity of the materials can be improved by designing the porosity in the molecule level, and a larger porosity ensures a stronger adsorption capacity. The results identified that this strategy was a promising solution to produce UiO-type PCPs based adsorbents with excellent adsorption performance for effective removal of toxic chemicals from wastewater and industrial sustainability, medical processes, and environment-related areas. |
