A study of photocatalysis of TiO2 coated onto chitosan beads and activated carbon

A study of photocatalysis of TiO2 coated onto chitosan beads and activated carbon Titanium dioxide has been thought of as a safe, effective light scatterer which is widely used in cosmetics, sunscreens, and even food as a whitening agent. The development of environmental purification technology using a TiO2 photocatalyst, which removes organic contaminants by forming OH radicals through redo reactions, has recently attracted great attention. While TiO2 is chemically activated when exposed to UV light in sunlight or a fluorescent lamp, it generates strong oxidization and deoxidization. In addition, TiO2 is used for various purposes because of its properties, such as not melting neither in acid nor alkaline conditions, generating great photochemical stability and strong oxidization, and has a wide range of application in industries. TiO2 can be easily found around us in wide usage such as a whitening pigment. In addition, there are many experiments going on in various areas using its properties such as disassembling of organic compounds, sterilizing, deodorizing and purifying water. Salmonella choleraesuis subsp. is an important component of the porcine respiratory disease complex (PRDC). The recognition of S. choleraesuis subsp. as an important and common cause of swine respiratory disease and the emergence of porcine reproduction and respiratory syndrome (PRRS) as a new swine disease have both occurred only relatively recently. The objective of this study was to evaluate the effect of bactericidal agents in the presence of TiO2 on selected typical food bacteria, S. choleraesuis subsp. However, TiO2 powder could not be used satisfactorily due to its poor separability from the suspension and flowability. Therefore, in this experiment TiO2 was coated on activated carbon and chitosan beads for the easy recovery of the photocatalyst from the system after photo-reactions. We established the response surface methodology (Box–Behnken design) to investigate the principal parameters such as TiO2 concentration, UV illumination time, temperature and pH for their influence on cell death. According to the result of the experiment, it was found that TiO2 is a strong anti-bacterial agent against S. choleraesuis subsp. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
