| Abstract: | Cu‐metal‐organic frameworks (Cu‐MOFs) were synthesized in one step using copper acetate, glutamic acid, and small‐molecular organic amines at room temperature. Organic amines served as modulators to modify the structure of Cu‐MOFs. Characterization results proved that the addition of modulators changes the surface morphology. Batch adsorption data indicated high adsorption capacities for anionic organic dyes with glutamic‐Cu‐triethylamine (Glu‐Cu‐TA), higher than that of most MOFs reported. An acid pH was the optimum adsorption parameter. The easy regeneration of recycled Cu‐MOFs suggested there were weak intermolecular interactions between Cu‐MOFs and dyes. The main adsorption forces included electrostatic interaction, ion exchange, π‐π complexation, and hydrogen bonds. |
