	Photodegradation of 4-chlorophenol in Continuous Micro Photo Reactor Drhová, Magdalena Fulltext: content.csg - PDF Plný tet: SKMBT_C22013082014330 - PDF Detailed record
	Performance of Continuous Micro Photo Reactor – Comparison with Batch Process Drhová, Magdalena ; Hejda, S. ; Křišťál, Jiří ; Klusoň, Petr Utilization of the flow chemistry as well as microreactors belongs to the latest trends in chemical engineering. Continuous microreactors of various kinds can be found in the literature, for example the micromixers, micro packed beds, or micro photo reactors. In order to evaluate the benefits of microtechnology application for the given process, the performance of a particular microreactor needs to be compared with the conventional setup. This contribution presents the performance of a continuous micro photo reactor in comparison with a batch process. Two model reactions were selected: the catalyzed photooxidation of 4-chlorophenol (4-CP) and the singlet oxygen chemical quencher 9,10-dimethylanthracene (DMA) in dimethylformamide. The tests were carried out using advanced opto-chemical apparatus with a well-defined light filter corresponding to the absorption bands of the used photo catalysts.

	Photochemical Degradation of Polybrominated Diphenyl Ethers in Micro Photo Reactor Vajglová, Zuzana ; Veselý, M. ; Křišťál, Jiří ; Vychodilová, Hana ; Tříska, Jan ; Jiřičný, Vladimír Most authors used for their studies of technical decaBDE mixture, or pure congener BDE 209. Very few studies used the technical octaBDE mixtures or pentaBDE, or congener BDE 47, which are most abundantly represented in the environment. Photodegradation of PBDE by catalysis over nanoporous TiO2 in microwave field showed very positive results. Debromination of BDE 209 after 240 minutes was very high and reached 99% (from initial value of 14 125 ng/mL). Lower brominated congeners including the tri brominated congener BDE 28 were safely determined. Fulltext: content.csg - PDF Plný tet: SKMBT_C22012102413500 - PDF Detailed record
