Box , Riyadh , Saudi Arabia. Metal organic frameworks MOFs are attracting significant attention for applications including adsorption, chemical sensing, gas separation, photocatalysis, electrocatalysis and catalysis. In particular, zeolitic imidazolate framework 8 ZIF-8 , which is composed of zinc ions and imidazolate ligands, have been applied in different areas of catalysis due to its outstanding structural and textural properties. It possesses a highly porous structure and chemical and thermal stability under varying reaction conditions. When used alone in the reaction medium, the ZIF-8 particles tend to agglomerate, which inhibits their removal efficiency and selectivity.

China E-mail: chunshengwu ZIF-8 nanoparticles were prepared with a convenient method at room temperature. The ZIF-8 nanoparticles were relatively stable under neutral and alkaline solutions, while their structure easily collapsed partially in the strong acidic aqueous solution. The adsorption kinetics and isotherms of ZIF-8 for tetracycline were evaluated in detail. The effects of key parameters such as pH, contact time, temperature and ionic strength on the adsorption of tetracycline were studied. The data on the adsorption of tetracycline on the ZIF-8 nanoparticles fitted well to the pseudo-second-order kinetics model, while the adsorption isotherm data can be explained respectively by the Langmuir isothermal model and the Freundlich isotherm model to varying degrees. The equilibrium quantity of tetracycline on ZIF-8 obtained in adsorption kinetic studies was This implied that the adsorption capacity of ZIF-8 to tetracycline can be improved to a large extent. Regeneration experiments indicated that the used adsorbent still showed excellent applicability after four rounds of recycling. Wu, Z. Xiong, C.
