摘　　要：建立了树脂工艺品中半挥发性有机物（SVOCs）的超声萃取-气相色谱检测方法。对超声萃取条件进行了研究，优化了气相色谱参数。结果表明，样品用三氯甲烷在60℃下超声萃取40min，选择HP-5色谱柱时，气相色谱（FID）测定半挥发物总量时可获得良好的灵敏度和准确的定量结果。方法的相对标准偏差小于5％（n=6），检测限为2mg／kg。4个含量水平样品的6个实验室3次平行测定结果表明，实验室内测定结果的相对标准偏差为1．61％～2．94％，实验室间测定结果的相对标准偏差为5．96％-8．35％。A method was developed for determination of the semi-volatile organic compounds（SVOC） in resin craft by ultrasonic extraction-gas chromatography（GC）. The ultrasonic extraction conditions were investigated and GC parameters were optimized. Test results showed that good sensitivity and accurate quantitative performances were achieved by GC-FID when the samples were ultrasonic-extracted with chloroform for 40 min at 60 ~C and HP-5 capillary was used. The relative standard deviations（RSDs, n=6） of actual samples were all less than 5% and the detection limit was 2 mg/kg. RSDs of the determination results for 4 content levels were 1.61%-2.94% by datas from a lab, and 5.96%-8.35% by datas from different labs, which were calculated according to the test results of 3 replicates by 6 labs.
