Green synthesis of iron-organic framework Fe-BTC using direct ultrasound to remove methylene blue dye

Abstract

Metal-organic framework materials (MOFs) comprise organic bridges and metal centers (as connection points). MOFs have unique properties such as crystal structure, large specific surface area, flexible structural framework, and can change the size and shape of pores and diverse chemical functional groups inside the pores. In this study, metal-organic framework materials based on iron (Fe) and the organic ligand H3BTC were successfully synthesized by ultrasonic method and evaluated for their ability to remove MB dye through Investigate the effects of MB concentration, pH, isotherm model, and adsorption kinetics. With a size of about 100 - 200 nm and an excitation wavelength in the ultraviolet region, the synthesized material shows potential in environmental treatment when the adsorption efficiency reaches over 60% after just 10 minutes and over 80% both processes under sunlight conditions. In addition, the synthesized material is also evaluated to have selective adsorption with Methylene Blue dye.
