Herewith, magnetic Zn MOF composite material was utilized as an efficient adsorbent for direct red 81 “DR81” dye from wastewater. The synthesized magnetic MOF was characterized using X-ray diffraction (XRD), field emission transmission electron microscopy (FETEM), Fourier-transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), thermal gravimetrical analysis (TGA), and Brunauer-Emmett-Teller (BET) surface area analysis. The adsorption profile of DR81 anionic dye onto the prepared magnetic MOF was investigated with various processing parameters such as contact time, dosage, and initial dye concentrations. The optimum dosage from the fabricated magnetic Zn MOF for decontamination of DR81 was 1.0 g l−1 at pH = 7 after 30 min. The maximum Langmuir monolayer adsorption capacity of the DR81 decontamination via the synthesized magnetic MOF was recorded 67.35 mg g−1. These promising data confirmed the availability of the synthesized magnetic MOF composite as an excellent adsorbent material for the adsorption of DR81 from aqueous media.
