 Abstract
In the following work we present the elaboration of a mathematical model to determine the adsorption rate of light in a photochemical reactor used for photooxidation of unsaturated fractions C10.
Chemical actinometers with potassium ferrioxalate and uranil acetate were used. A correlation between the wavelength of light radiation and the quantum yield of the photooxidation reaction was obtained.

 Rezumat
În lucrarea de faţă se prezintă un model de calcul pentru a determina viteza de absorbţie a radiaţiei luminoase într-un reactor fotochimic folosit pentru fotooxidarea fracţiilor nesaturate C10.
Se folosesc actinometrii chimici cu ferooxalat de potasiu şi acetat de uranil. S-a obţinut o corelaţie între lungimea de undă a radiaţiei luminoase şi randamentul cuantic al fotooxidării.
