摘　　要：采用尿素法制备了锌-铝水滑石,并通过高温煅烧得到了焙烧水滑石。通过表面酸碱滴定实验进行了材料表面性质研究,并进行了吸附抗生素实验。结果表明,由于焙烧水滑石良好的质子化和脱质子化能力,从而与抗生素表面形成羟基,从而达到很好的吸附效果。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.
