Pressurised liquid extraction (PLE) was used to extract DDT [1,1,1,-trichloro-2,2-bis(p-chlorophenyl)ethane] and its metabolites, DDD [1,1-dichloro-2,2-bis(p-chlorophenyl)ethane] and DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene] from an aged, contaminated soil. Using three sequential static phases, PLE removed an equivalent quantity of DDT and its metabolites as Soxhlet extraction, in less time and with less solvent. Recovery was almost quantitative, implying appropriate sample work-up and manipulation.
采用加压液体萃取（PLE）法从一块老化的受污染土壤中提取滴滴涕[1,1,1-三氯-2,2-双（对氯苯基）乙烷]及其代谢物滴滴滴[1,1-二氯-2,2-双（对氯苯基）乙烷]和滴滴伊[1,1-二氯-2,2-双（对氯苯基）乙烯]。通过三个连续的静态阶段，PLE在更短的时间内使用更少的溶剂，提取出了与索氏提取法等量的滴滴涕及其代谢物。回收率几乎是定量的，这表明样品处理和操作得当。
