摘要：

In this study, we have successfully synthesized aerogel composite materials based on PVA/ Maltodextrine/Agar in combination with montmorillonite (AE2) using tetracycline antibiotic (TCC) adsorption in water. The structural properties of the materials were evaluated by the following methods: XRD. SEM, FTIR, BET. Survey results of TCC antibiotic adsorption showed that the highest adsorption capacity reached 90.37 ppm in the following conditions: pH 2, initial TCC concentration 120 mg/l, adsorbent dosage 0.003 g/L, 60 min adsorption time. The experimental data are consistent with the pseudo-first-order kinetic model and the Langmuir kinetic model. Overall, the results show that the composite aerogel (AE2) exhibits potential antibiotic adsorption applications in contaminated water.
