The Department of Chemistry at the Faculty of Science discussed, on Monday, August 31, 2026, the doctoral dissertation tagged ” preparation of clay–biochar overlays and their use as sustainable adsorbents and catalysts”, submitted by doctoral student Esraa Ali Hassan, specializing in industrial chemistry, in the Hall of Professor Dr. Saadallah Tawfik. The aim of the study was to prepare sustainable composites from locally available raw materials, including kaolin clay and walnut shells, using acetic chloride and ferric chloride as activating agents, and employing the prepared composites in multiple environmental and industrial applications. The compounds were used as adsorbents to remove methylene [Read More]
