In general, the photoexcitation process induces reduction and oxidation to the electrons in the conduction band and the electrons in the valance band. [ 75 ] As a result, the valance band holes and their electron pair transfer to the surface, where the photo‐generated electrons could react with the dissolved O 2 are adsorbed on the surface to yield .…”

Increasing living standards, urbanization, industry, and inadequate wastewater management are all contributing factors in the release of toxic wastewater into the aquatic environment.The industrial sectors producing dyes and pigments are seen as major environmental hazards due to the vast amounts of water they require throughout the manufacturing process. [1][2][3] Toxic organic pollutants, such as fertilizers, chlorinated solvents, and volatile organic compounds (VOCs), as well as nitroaromatic compounds, phenols, and dye-based chemicals, are already poisoning natural water sources. [4,5] Organic dyes, for example, are widely used in the textile industry, jute and threads industries, pharmaceutical industries, petrochemical industries, and other sectors and are discharged as effluent into water resources such as ponds, lakes, rivers, and other bodies of water. These organic dyes and their products are typically poisonous, and they have the potential to induce significant mutagenesis and carcinogenic consequences when they come into contact with living organisms. [6,7] Treatment of water contaminated with different chemical and biological pollutants has been accomplished via a variety of methods such as biological treatment, activated carbon adsorption, ultrafiltration, reverse osmosis, and electrochemical oxidation.

“…The peak at 530 eV is assigned to the oxygen ions involved in the crystal lattice of cobalt ferrite (O spinel ), and that at 531.3 eV corresponds to the O − or O 2 2− species adsorbed on the surface, related to the oxygen vacancy inherent to the surface. The peak at 532.2 eV corresponds to the adsorbed water (the O–H bond) [ 40 ]. The peak at 535.13 eV is associated with the carbon single-bonded to the hydroxyl group (C–OH).…”

The paper presents the synthesis and characterization of new cobalt ferrite-lignin hybrids. The hybrids were obtained through the combustion of cobalt nitrate and ferric nitrate, two kinds of lignin being used as combustion agents. The temperatures of calcination were 500 °C and 900 °C, respectively. The hybrids were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS). The magnetic properties were also assessed by vibrating sample magnetometer system (VSM). This facile synthesis method made it possible to obtain cobalt ferrite-lignin hybrids with a spinel structure. Their particle sizes and crystallite sizes have increased with an increment in the calcination temperature. A different occupancy of cations at octahedral and tetrahedral sites also occurred upon the increase in temperature. The hybrids comprising organic lignin presented the best magnetic properties.
