A mixture of Aroclor 1260 and p,p'-DDT was irradiated at 254nm by UV lamp (40W) in the presence of TiO"2 (30mgmL^-^1 non-aqueous solution). Comparison of gas chromatograms showed that p,p'-DDT signals decreased significantly after irradiation, while Aroclor 1260s chromatograms did not show any difference before and after irradiation. Detection limits were 0.30mgL^-^1 and 0.15mgL^-^1 for p,p'-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. |
