Abstract

The photocatalytic degradation of contaminants on soil surfaces using ultraviolet light source (310 nm) in the presence of TiO2 was investigated. The degradation was studied on real polluted soil samples containing a mixture of aliphatic long chain hydrocarbons. Photocatalytic experiments were carried on in a photo chamber, in which the temperature did not exceed 31°C. The results demonstrate that the photodegradation of organic compounds is extremely difficult
