Prokopenko S. Photoozonolysis of organic molecules on the surface of highly dispersed silica and titanium dioxides

This Thesis is dedicated to establishment of interrelation between the conditions of the reaction of the photoozonolysis and effectiveness of destruction of the organics compounds; finding an optimal oxidation conditions of the organics in multicomponent water solution in the presence of silica or titanium dioxide. The acceleration of the process of ozonolysis in molecules of antracene and eozine of the surface of silica dioxide was proved utilizing the method of spectral-kinetic fluorescence. Was established that the process of the oxidative destruction coumarin-30 on the surface of silica and titanium dioxides is multistages and undergo through formation of the intermediate - diprotonated form of coumarin-30, speed of oxidation of which is slower comparing to initial coumarin-30. Was shown that an increase of temperature decreases destruction processes in formaldehyde and promotes the formic acid accumulation, which indicates multistage process of the formaldehyde destruction
