Abstract:
Removing pollutants of water and, in general, wastewater treatment is one of the most important issues in the world. In this research, we synthesized a nanophotocatalyst based on znic-iron in the form of a magnetic core-shell Fe3O4@ZIF-8, and used to degrade the malachite green toxic color of wastewater. SEM, XRD and FT-IR analyzes have been taken and analyzed fore all three core, shell and core-shell composite catalysts.Due to the band gap of core-shell nanocomposite and the performance of the malachite green dye, a photocatalytic process under the visible light was obtained, which at an optimum amount of photocatalyst 0.003g, we reach 99.2% dye degradation at the 30ppm concentration. This malachite treatment is carried out at 4.6pH, which is normal pH of the soluble. Using a magnetic base on one side, and a high adsorbance shell ZIF-8 in the physical adsorption process one the other, has led to an optimal performance with the high photocatalytic activity of this core-shell nanocomposite
