| 摘 要： | 土壤、植物和籽实样品分别用四氢呋喃、甲醇、乙酸乙酯以超声技术提取。提取液经旋转浓缩蒸发仪浓缩，经硅胶柱净化后，由高效液相色谱（ＨＰＬＣ）分离，萤光检测分析。对于土壤、植物和籽实样品，其方法回收率根据各个ＰＡＨ化合物的理化性质不同分别为４５．６８－９３．４２、７７．５９－１０８．１３和７９．１１－９８．９６％，结果表明，二氯甲烷、四氢呋喃适合作为土壤样品的提取剂；甲醇、乙酸乙酯分别适合于植物和籽实样

| Abstract: | Soil, plant and seed samples are respectively extracted by tetrahydrafuran, methanol andethyl acetate ultrasonically. The extracts are evaporated by rotary evaporator, cleaned upon silica gel column and analyzed on HPLC with fluorescence detector. The recovery ofPAHs is 45. 68-93. 42% for soil, 77.59-108.13% for plant, and 79.11-98. 96% forseed, depending on the physico-chemical properties of individual PAH compounds.Dichloromethane and tetrahydrafuran are the suitable extracting agents for soil, andmethanol and ethyl acetate for plant and seed. respectively. This method has the characteristics of simplicity, rapidity, sensitivity and reliance, and can be used for the study ofPAHs in soil-plant system. |
