Abstract: A research study was conducted to evaluate the effectiveness of a newly synthesized bionanoadsorbent in removing oil from wastewater. Shirvan oil was used in our experiment to extract oil from the aquatic environment as part of our research work. The hazelnut shell was used as a bioadsorbent to remove Shirvan oil from water experimentally. In our research work, the synthesis process of a bio-nanoadsorbent incorporating Fe3O4 nanoparticles was carried out to enhance the efficiency of the bioadsorbent and its adsorption capabilities. To test the adsorption assay for the synthesized biosorbent and bionanoadsorbent, the optimal adsorption time, optimal temperature, and pH were determined. The optimal adsorption time was determined to be 30 minutes for the biosorbent and 12 minutes for the bio-nanoadsorbent (61.25% and 92.5%). SEM analysis of bio-nanoadsorbents synthesized from hazelnut shells and hazelnut shell-Fe3O4 nanoparticles revealed that the Fe3O4 nanoparticles wholly covered the surface of the hazelnut shells. It was also determined that the agglomeration of Fe3O4 nanoparticles inside hazelnut shells is due to the monodisperse and homogeneous distribution of nanoparticles.
