Abstract
A photocatalytic degradation method was developed for polychlorobiphenyl (PCB) and organochloride pesticide (OCP) discrimination and quantification. A mixture of Aroclor 1260 and p,pâ²-DDT was irradiated at 254 nm by UV lamp (40 W) in the presence of TiO2 (30 mg mLâ1 non-aqueous solution). Comparison of gas chromatograms showed that p,pâ²-DDT signals decreased significantly after irradiation, while Aroclor 1260s chromatograms did not show any difference before and after irradiation. Detection limits were 0.30 mg Lâ1 and 0.15 mg Lâ1 for p,pâ²-DDT and Aroclor 1260, respectively. The method was applied to spiked egg samples, the recoveries were found as 72% for DDT and 82.01% for Aroclor 1260.
