Abstract

The photodegradation of n - nonane hydrocarbon (C9H20) by TiO2 was investigated. High pressure Hg - lamp with metal halide additive (Type 150 Z2 Huna Immersion Lamp) was used as irradiation source (200-600) nm. in a thermostatic vessel ( 250 ml.) at 298 K. Many parameters on the photocatalytic degradation processes has been explored in order to find the optimum conditions for this photocatalytic processes such as: the concentration of TiO2, TiO2 particle size, the effect of dissolved gases and it is types. Gas chromatographic technique using FID was used to identify the photocatalytic products of hydrocarbons .The predominant product of the present photocatalytic system were C5, C6, and C7 hydrocarbones when oxygen gas was used as purging gas. According to the experiments results obtained , the kinetic experiment, mechanisms of the photodegradation processes of n- nonane by the conditions employed were suggested. .
