20.500.12556/DKUM-66659 Kinetic studies of catalytic ozonation of atrazine Kinetičko istraživanje katalitičkog ozoniranja antrazina The aim of our work was to degrade atrazine by the ozone treatment of both a model and the original drinking water samples, using Pt-catalyst, and to evaluate the performance of this catalyst. The rate constant for the reaction of atrazine with ozone was determined in the model water sample. The activation energies and the reaction orders of ozone decomposition were determined in both the model and the drinking water samples. Ozone treatment using Pt-catalyst has some influence on the loss of atrazine in the sources of drinking water. The concentration of some metabolites in the model and drinking water was observed during ozone treatment. The toxicity of atrazine to crustacean Daphnia magna in the original drinking water and in the ozone treated water samples was also assessed. Cilj ovog rada bio je istražiti raspad atrazina ozoniranjem uzoraka modelne i izvorne pitke vode korištenjem Pt-katalizatora, te određivanje učinkovitosti tog katalizatora. Konstante brzine raspada atrazina katalitiziranim i nekataliziranim ozoniranjem su određene samo za uzorke modelne vode, a aktivacijska energija i red reakcije u odnosu na ozon su određeni za obje vrste uzoraka. Katalizirano ozoniranje utječe na raspad atrazina u uzorcima pitke vode. Tijekom ozoniranja praćene su koncentracije nekih metabolita u uzorcima modelne i pitke vode. Određena je toksičnost uzoraka originalne pitke i modelne vode na račiću Daphnia magna. ozone Pt-catalyst atrazine water treatment waste water kinetics ozon Pt-katalizator atrazin kinetika odpadne vode čiščenje odpadnih voda true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-05 10:25:20 2017-07-05 10:26:40 2022-08-01 13:01:05 2019-07-11 15:54:40 2008 0 0 str. 673-679 št. 4 Letn. 81 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0011-1643 543.3:544.4 22807 12902678 0011-1643 URN:SI:UM:DK:7QGZYO9D Croatica_Chemica_Acta_2008_Tepus,_Simonic_Kinetic_Studies_of_Catalytic_Ozonation_of_Atrazine.pdf Croatica_Chemica_Acta_2008_Tepus,_Simonic_Kinetic_Studies_of_Catalytic_Ozonation_of_Atrazine.pdf 1 6DBC894D25B9330DD95368D00C614F99 e3c5382027dbeecbabbe347d51e465093e5c27669634b4cc59d8f7606e1c3e2e 5b558360-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/d8316b6e-9ff8-4f67-b235-c8964ca49575 https://dk.um.si/Dokument.php?lang=slv&id=113667 http://hrcak.srce.hr/31195 1 https://dk.um.si/Dokument.php?lang=slv&id=113666 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
