Simple preparation of floating magnetic particles for oil recovery using the ferrite production process in the presence of long-carbon-chain surfactants.

This study developed a simple, low-cost, and low-energy method for preparing floating magnetic particles (FMPs) for oil recovery, characterized the prepared FMPs, and evaluated their oil recovery performance. It has been established that the production of iron hydroxide in the presence of anionic surfactants with alkyl chains with 12 or more carbon atoms, e.g.

Photocatalytic degradation of rhodamine B dye pollutants by FeO/SiO core-shell magnetic nanocomposite functionalized with TiO.

Significant efforts have been dedicated to creating recyclable and efficient methods for treating waste dyes, including rhodamine B (RhB). Nevertheless, challenges such as complex operational techniques, high costs, energy consumption, and inefficacy in dye removal persist. Here, the synthesis and application of TiO/FeO/SiO for photocatalytic degradation of RhB dye pollutants have been explored.

Photocatalytic degradation of naphthol blue from Batik wastewater using functionalized TiO-based composites.

This work provides a first-time comparative study examining the photocatalytic activity of functionalized TiO-based composites to eliminate naphthol blue in Batik wastewater. Reduced graphene oxide (RGO) was synthesized by oxidizing solid graphite using the Hummers' method followed by sonication and reduction. N-doped TiO (N-TiO) was synthesized from titanium tetrachloride (TiCl) and urea (CH₄N₂O) precursors by the sol-gel method.

Simultaneous photocatalytic removal of organic dye and heavy metal from textile wastewater over N-doped TiO on reduced graphene oxide.

Methylene blue (MB) and hexavalent chromium(Cr(VI)) are hazardous pollutants in textile waste and cannot be completely removed using conventional methods. So far, there have been no specific studies examining the synthesis and activity of N-TiO/rGO as a photocatalyst for removing MB and Cr(VI) from textile wastewater. This work especially highlights the synthesis of N-TiO/rGO as a photocatalyst which exhibits a wider range of light absorption and is highly effective for simultaneous removal of MB-Cr(VI) under visible light.
