Identification of Magnetic Fe₃O₄ Nanoparticles by Artemisia Absinthium Extract

Nanomaterials have become one of the innovative research directions in materials science, biochemistry, and medicine. Small nanoparticles (NPs) lead to the development of branches of science in very small-scale dimensions, such as nanotechnology ushering in more advanced levels of research in its field. Fabrication and use of nanometer-sized materials are increasingly growing, considering their interesting industrial properties; however, nanoparticles taken from chemical compounds are now focused attention in research as they may contain hazardous and toxic chemicals and may generate risks when applying green chemistry principles. This study aimed to identify magnetic Fe₃O₄ nanoparticles by Artemisia absinthium extract.

FT-IR, FESEM, and XRD TEM techniques were used to identify the synthesized nanoparticles. The parameters examined in this study included removal time, pH, and level of nanoparticles; each was 15-45 minutes, 5-9, 0.1-0.05 grams, respectively. The findings from a real sample suggested a 70% removal which consequently increased as the nanoparticle level rose by up to 0.1 gram. Under standard conditions, 94.78% and in a real sample, up to 71% of tetracycline was removed from the medium.The findings showed that a significant portion of tetracycline could be removed by Artemisia absinthium extract-modified magnetic Fe₃O₄ nanoparticles, making this research a practical work in sewage treatment plant-related issues.
