A scientific seminar dedicated to March 27 – Science Day was held at the Faculty of Ecology and Soil Science of Baku State University (BSU).

At the event, doctoral student of the Department of Environmental Chemistry Ulker Nagiyeva presented a report titled “Oil-Contaminated Water Treatment Using Bio-Nanoadsorbents Based on Waste-Free and Low-Waste Technologies.” She noted that pollution of water by oil and petroleum products remains one of the most serious environmental challenges today.

The research focuses on the development of new bio-nanoadsorbents for oil purification based on hazelnut shells and Fe₃O₄ nanoparticles. Hazelnut shells, a widely available plant waste in Azerbaijan, have strong potential for effective reuse. Fe₃O₄ nanoparticles used as nanofillers are cost-effective, non-toxic, and possess high sorption and superparamagnetic properties.

The structure of the synthesized materials was studied using modern research methods, including scanning electron microscopy, infrared spectroscopy, and thermogravimetric analysis. The results demonstrated the relationship between the structure and sorption properties of the adsorbents.

It was also noted that the research is conducted under the supervision of Sevinj Hajiyeva, Doctor of Chemical Sciences, and Flora Hajiyeva, Doctor of Chemical Sciences, Associate Professor.
