Description
The photo catalytic degradation of hazardous waste like chlorinated paraffin compound (1,12-Dichlorodoecane Ded) was investigated in different aquatic media using GC-MSD. The direct photolysis of Ded in HPLC water was considered to be negligible (k = 0.0020+-0.0007h-1). An acceleration of the photodegradation rate was occurred in presence of different TiO2 catalyst systems. Molecular oxygen was found to play a vital role in the degradation process. Anatase TiO2 was proved to be the most efficient one (k=0.7670+-0.0876h-1), while the rate constant of the rutile TiO2 was calculated to be 0.2780+-0.0342h-1. Improvement of photo catalytic efficiency of rutile TiO2 was achieved by addition of Fe+2 giving a rate constant =0.6710+-0.0786h-1
