In this study, we have taken a novel approach to dye removal and real wastewater treatment by employing dual smart strategies: surface charge transfer engineering and developing an easily recoverable photocatalyst. The removal of acid blue 92 (AB92) dye by using a novel 3D polypyrrole-zinc oxide-sodium alginate (PPy-ZnO-SA) nanocomposite under UV-C, visible light, and natural sunlight was investigated. The nanocomposite hydrogel was characterized using various techniques, including XRD, Raman, FESEM, TEM, XPS, PL, DRS, and CV analyses, and the type of effective interactions in different stages of removal was investigated by FTIR analysis.

This study sought to purify real wastewater and water tainted with methylene blue (MB) by immobilizing ZnO nanoparticles onto an alginate matrix using a straightforward approach and a three-dimensional structure. After analyzing the impact of , it was determined that 93.

The interaction of conducting polymer and titanium dioxide (TiO) leads to the exchange that enhances the alteration of the semiconductor's surface and subsequently decreases the bandgap energy. Polypyrrole (PPy) and TiO nanocomposites have promising potential for photocatalytic degradation.

We characterized the structure and morphology of synthesized magnetic adsorbent by Fourier transform infrared spectroscopy (FTIR), FESEM, and XRD. The FTIR and XRD tests confirmed the collagen fibers, apatite crystals, and nanomagnetite particles presence in the MFS structure.

The structure and morphologies of the xanthan-based hydrogels were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). Adsorbents comprised a porous crosslink structure with side chains that carried carboxyl, hydroxyl and sulfonate.
