An approach for cationic dyes removal from wastewater: Green synthesis of iron nanoparticles using Prunus avium stems extracts

Metallic nanoparticles with optical, electrical, catalytic, magnetic, and biological properties are structures that can be used in environmental pollution. The use of iron nanoparticles in environmental rehabilitaion is gaining interest due to their large surface area to volume ratio. The aim of this study is to synthesize and characterize iron oxide nanoparticles by using cherry plant extracts through a green synthesis approach, and to evaluate the use of cherry plant extracts as an adsorbent of methylene blue in wastewater. The physicochemical characterization of nanoparticles was performed with UV–Vis, FT-IR, XRD spectroscopies, SEM microscopy and Zetasizer particle size analysis. As a result of the experiments, the adsorption percentage increased depending on the time and 67.34% methylene blue removal was achieved at the 150th minute. This study highlights the importance of innovative approaches and the increasing use of biocompatible, environmentally friendly, and economical green materials in applications.
