Synthesis of Iron Nanoparticles Using Psidium guajava Leaf Extract and It’s Role in Crystal Violet Dye Removal

Abstract

Green process techniques have been favored in recent years due to their influence on wastewater removal, and they are being emphasized in the advancement of nanotechnology. Eco-friendliness and abundance in nature make green materials preferable in nanoscience. Psidium guajava leaf extract was employed in this study to manufacture ecologically friendly iron nanoparticles. The FeNPs are used in the removal of Crystal violet dye which is used in textile industries and as a disinfectant. It is known to cause animal carcinogenicity and permanent skin coloring in humans when in Contact. There is a need for removal from natural bodies frequently used by living beings. FTIR, SEM, XRD, and EDX are used in the characterization of iron NPs from Psidium guajava, and the benefits of green synthesis are observed. Adsorption studies in batch format are used for the removal of a textile dye from an aqueous solution. The Studies are done considering parameters of Contact time, pH, Initial dye concentration, adsorbent dosage, and temperature. The removal efficiency obtained by plant-synthesized Iron NPs for Crystal violet dye is around 99%. We attempted to create an eco-friendly, less energy-intensive, and more effective approach for textile dye degradation.
