Description
  • Any kinetic description of a (photo)chemical reaction primarily involves a mathematical analysis showing how the concentration of the (photo)reactant depends on time. The simplest case of (photo)reaction is a (pseudo)monomolecular one. Unlike the kinetic model of (pseudo)monomolecular chemical reaction, the general analytical solution of mathematical model of photochemical reaction is, depending on experimental conditions, much more complicated or even impossible. In the present study, an approximation of the integral kinetic description of (pseudo)monomolecular photolysis has been developed, using high conversion and polychromatic irradiation. Potassium ferrioxalate was used as a model photo-reactant. Its photolysis was carried out both in a differential through-flow and an annular integral reactor. Medium pressure Hg arc lamps were used as polychromatic light sources in both cases.

  • Každý kinetický popis fotochemické reakce zahrnuje matematickou analýzu, která ukazuje závislost koncentrace reaktantu na čase. Nejjednodušším případem je monomolekulární reakce. Na rozdíl od kinetického modelu monomolekulární chemické reakce obecné analytické řešení matematického modelu fotochemické reakce je v závislosti na experimentálních podmínkách daleko složitější anebo nemožné. V této práci byla navržena aproximace integrálního popisu monomolekulární fotolýzy za vysoké konverse a s použitím polychromatického záření. Jako modelový fotoreaktant byl použit ferrioxalát draselný. Jeho fotolýza probíhala v diferenciálním průtočném reaktoru a v integrálním reaktoru. Jako zdroj záření byla použita Hg středotlaká výbojka. (cs)
