Metal–organic frameworks (Sm-MOFs) were prepared using a microwave-assisted ball milling method with a water solution. The structure was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and SEM, and the thermal stability of the Sm-MOFs was tested by Thermogravimetry (TGA). The results showed that the Sm-MOF material exhibited a favorable effect on removing the organic dye Congo red (CR). When the concentration of CR was 80 ppm, adding 50 mg of Sm-MOF material achieved an adsorption capacity of 396.8 mg·g−1. The experimental data were analyzed theoretically through dynamics, and the experimental results were consistent with the second dynamics model, with correlation coefficients (R 2) all above 0.99. Comprehensive data analysis revealed that the Sm-MOF materials had great potential for future application in wastewater treatment.
