Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a method for the determination of DDT and 666 residues in milk by gas chromatography. The method is extracted with acetone-n-hexane and purified with concentrated sulfuric acid. The recovery rate of samples added with different 666 isomers (0.004-0.008ppm.) and DDT and its metabolites (0.01-0.0ppm) was 83.4%-99.8%. This method is simple, fast, and does not require the use of expensive adsorbents.
