摘要:A preparation method and an application of a clay/tannic acid/metal ion composite material for efficient adsorption of antibiotics are provided, which relate to the field of water environment treatments. A clay/tannic acid/metal ion composite adsorbent is prepared, preparation method and operation process are simple, synthesis time is short, and yield is large. A raw material used is tannic acid, which has a wide range of sources, is non-toxic, biodegradable, and has no risk of secondary pollution, due to abundant phenolic hydroxyl groups in tannic acid, the tannic acid can not only chelate with the metal ions, but also adsorb pollutants from water, when combined with the clay and the metal ions, a composite body is formed, which has a rougher surface, and adsorption active sites are increased, thereby effectively increasing adsorption, and improving an adsorption performance for pollutants. The clay/tannic acid/metal ion composite adsorbent has good adsorption effect for antibiotics.
