摘　　要：以三氯甲烷为萃取溶剂,超声萃取纸品中的邻苯二甲酸酯类增塑剂,提取产物进行气相色谱/质谱-选择离子监测法测定,从而建立了一种同时测定纸品中21种邻苯二甲酸酯类增塑剂的方法。该方法简便快捷、灵敏度高、定性定量准确。该方法的平均回收率为81.98%～106.82%,精密度试验相对标准偏差(RSD)为2.11%～9.75%。DIDP和DINP的检出限分别为2.0、1.0mg/kg,其余各组分的检出限均小于0.4mg/kg。采用该方法对市售涂布纸进行测定,结果在部分涂布纸中检出邻苯二甲酸酯类增塑剂。An analytical method was established for the simultaneous determination of phthalate plastics in papers. Phthalate plastics were ultrasonically extracted using trichloromethane as the extraction solvent, then the extratives were analyzed by applying gas chromatography -selected ion monitor technique. The proposed method was rapid, accurate and sensitive. The spiked average recoveries varied from 81.98% to 106.82% while the relative standard deviation （RSD） of precision experiment changed from 2.11% to 9.75%. The detection limits of DIDP and DINP were 2mg/kg and 1 mg/kg, respectively. The detection limits of other phtbalate plastics were all less than 0.4mg/ kg. Phthalates plastics in commercially available coated papers were detected and the results showed that phthalate plastics existed in some commercially available coated papers.
