摘要
The Gum Ghatti (GG)/Konjac Glucomannan (KGM)/zeolitic imidazolate framework-8 (ZIF-8) composite aerogels (GKZ) were synthesized by the sol-gel method and the vacuum freeze-drying method for effective removal of ciprofloxacin (CIP) from contaminated water. The results showed that the addition of different concentrations (0, 0.4, 0.6, 0.8 wt%) of GG could promote homogeneity but weakened the molecular interaction of the aerogel system without water. Remarkably, the ZIF-8 maintained the crystal structure, as well as its dispersion on the surface of aerogel, was significantly improved. Additionally, it was also found that the incorporation of moderate GG was favored regarding CIP adsorption, and GKZ with 0.6 % GG (GKZ0.6) exhibited the highest adsorption capability for CIP around 1035.4 mg/g. Besides, the effects of various ions, ionic strength, and pH on CIP adsorption were also investigated, which provided the reference for guiding the utilization of GKZ0.6. Furthermore, at fewer cycles, the adsorption efficiency of GKZ0.6 on CIP showed less loss. These features revealed that the GKZ composite aerogels might be a promising adsorbent for CIP removal from water.
