| 英文摘要 | A modified method was developed for the determination of dichloro. diphenyl-trichloroethane (DDTs) in high-contaminated soil. The samples were separated by accelerated solvent extraction (ASE), purified and concentrated by SPE, and determined by GC. The results showed that the average recoveries of DDTs in soil ranged from 84.0% to 105.3% with the RSDs of 1.3%-8.8%. IDL were 0.010-0.030 mu g/kg, and MDL was 0.30-0.50 mu g/kg. Furthermore, Tenax-TA was used to extract DDTs from successively oxidized soil. After successive oxidation for four times, Tenax-TA extraction of p, p'-DDE, p, p'-DDD, o, p'-DDT, p, p'-DDT and total DDTs desorption respectively were less than 6% and the changes were not significant (p > 0.05). This method could be adopted to assess the potential environmental release risk of organo-chlorine pesticides (OCPs) and served as an assistant predictor of soil oxidation remediation end-point. |
