In recent years, the increasing demand for clean and potable water has created a need for efficient, cost-effective wastewater treatment. One of the most promising methods is heterogeneous photocatalysis due to its ability to mineralize organic mols. This paper describes the development of a flow-through packed bed reactor system based on a packed column comprising glass beads coated with com. available TiO2 (P25). The resulting deposited films and corresponding powders were characterized using thermal anal. (TGA-DSC-MS), X-ray diffraction (XRD), scanning/transmission electron microscopy (SEM/TEM), sp. surface area (BET) and XPS measurements. The photocatalytic efficiency of the reactor was tested by observing the degradation rate of Plasmocorinth B, an organic dye, and 18 bisphenols co-dissolved in deionized water and simulated wastewater under UV light. The developed photocatalytic reactor effectively removed organic dye and bisphenols from the aqueous medium using a combination of adsorption and photocatalysis. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Quality Control of 4,4′-Methylenediphenol).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Quality Control of 4,4′-Methylenediphenol
