摘要：

Organic dyes can be used as raw materials for food, printing and textile, closely related to human life. Herein, three iron-based organic frameworks were synthesized and characterized. The adsorption of three dyes, Methylene Blue (MB), Rhodamine B (RhB) and Malachite Green (MG), on three MOFs were discussed from the perspectives of adsorption isotherms, kinetics and regeneration.The results showed that all adsorptions are more in line with the Freundlich isotherm adsorption and the pseudo-first -order model. In addition, the removal rate of iron-based MOFs to dyes can still reach more than 85% after 5 cycles of use. It was also found that all three MOFs showed selective adsorption, with MOF-1, MOF-2 and MOF-3 showing the best removal efficiencies only for MB, RhB and MG, respectively, which are 94.8%, 91.3% and 92.6%.
