Preparation method and application of functionalized uiO-66 / sodium alginate microspheres

Abstract

This invention provides a method for preparing functionalized UiO-66 / sodium alginate microspheres, specifically including the following steps: Step 1, preparing functionalized UiO-66 powder; Step 2, preparing functionalized UiO-66 / sodium alginate microspheres using the functionalized UiO-66 powder; Step 1 specifically includes the following steps: Step 11, adding a certain amount of zirconium chloride and terephthalic acid to a certain amount of N,N-dimethylformamide; Step 12, adding a certain amount of hydrochloric acid, a certain amount of acetic acid, and a certain amount of 2-hydroxyphosphonoethyl acetate to the solution of Step 11. Acid is stirred in a constant temperature water bath for a period of time; Step 13: The solution obtained in Step 12 is transferred to a reaction vessel, and then the reaction vessel is placed in an oven at a certain temperature for a period of time; Step 14: After the reaction vessel cools down, the liquid in the reaction vessel is transferred from the reaction vessel to a centrifuge tube and centrifuged to obtain a white powder; Step 15: The white powder is washed alternately with N,N-dimethylformamide and methanol a certain number of times; Step 16: The washed white powder is placed in an oven at a certain temperature for a period of time to dry, thereby obtaining functionalized UiO-66 powder.
