| Abstract: | zinc-aluminum hydrotalcite was prepared by urea method, and calcined hydrotalcite was obtained by high temperature calcination. the surface properties of the material were studied by surface acid-base titration experiments, and the adsorption of antibiotics was carried out. the results show that due to the good protonation and deprotonation ability of calcined hydrotalcite, hydroxyl groups are formed with the antibiotic surface, thus achieving a good adsorption effect. |
