Preparation of Zn-MOFs by microwave-assisted ball milling for removal of tetracycline hydrochloride and Congo red from wastewater

In this study, we prepared Zn-MOFs as an ordinary, low-cost, and efficiency method taking advantage of zinc(II) acetate monohydrate and 1,3,5-benzene-tricarboxylic acid in microwave-assisted ball milling. The Zn-MOFs were measured via scanning electron microscopy, infrared spectrometry, X-ray diffraction, and thermogravimetry. We explored its use as a photocatalyst for the degradation of tetracycline hydrochloride and Congo red from aqueous solutions. The results demonstrate that the kinetic model was appropriate for the removal of organic pollutants. In general, it is feasible, inexpensive, and effective to use metal organic framework (MOF) to treat waste liquid. Therefore, our findings indicate that Zn-MOFs have broad application vista in wastewater purification.

Automated summary

In this study, Zn-MOFs were prepared using microwave-assisted ball milling and investigated for their photocatalytic degradation of organic pollutants in wastewater. The results showed that Zn-MOFs have great potential for efficiently treating waste liquid.
