Nanoparticles TiO2 Doped with Ag for Cationic Blue GRL Sewage Photocatalysis Color Disposal, Antimicrobial Properties, Kinematic, and Items Assessment

Cationic Blue GRL, BB 41 dye, caused more toxic harm to sewage when it was utilized to dye and print textiles. Dopant (TiO ₂ doped with Ag) nano-specimens were prepared with different Ag (0.01, 0.03, 0.05, and 0.07 mol%) by effectively utilizing a preliminary humid impregnation. The diffuse reflectance spectroscopy spectrum's surface plasmon resonance feature confirmed the amount of Ti ^4+, and Ag ⁺ charged particles was significantly diminished. The undoped TiO ₂ and TiO ₂ doped with Ag nanoparticles characterized by Scanning electron microscope (SEM), Transmission electron microscope (TEM), High-resolution transmission electron microscope (HRTEM), Energy Dispersive X-ray (EDX), X-ray diffraction (XRD), Nitrogen (N ₂ ) adsorption-desorption evaluates, and the band gap structure (GGA+U calculations). Several impacts encompassing pH, duration of contact, original BB 41 instances, the level of H ₂ O ₂ , temperatures, and the amount of TiO ₂ doped with Ag nanomaterial photocatalyst influence the photodegradation efficiency percent and the rate of degradation for BB 41. The kinetics of adsorption developed as four rates (Pseudo-first, Pseudo-second, Intra-particle diffusion, and Elovich) at various original BB 41 instances were investigated. Compared to these calculations, Pseudo-first was more effective, indicating a potential physisorption mechanism for the adsorption. The adsorption developed by the three isotherms examined (Langmuir, Freundlich, and Temkin) for the BB 41 adsorption. Compared to these calculations, Langmuir's equation matched more effectively. The disc diffusion test was used to measure the antimicrobial activity of undoped TiO ₂ and various amounts of Ag-doped TiO ₂ nanoparticles. These bacteria included a pair of gram-positive (Bacillus subtilis and Staphylococcus aureus), and one gram-negative (Escherichia coli). Furthermore, the reusability and regeneration of Ag-doped TiO ₂ nanoparticles under ultraviolet (UV) radiation was demonstrated.
