| 摘 要： | 研究并建立了水产品中的7种多氯联苯残留的气相色谱检测方法，用该方法对鱼、虾、贝、蟹、甲鱼等多种水产动物中多氯联苯的残留量进行了分析测定。结果表明，7种多氯联苯的峰面积与其质量浓度在1.0～200ng／mL范围内呈线性关系，相关系数均大于0．999。鳕鱼和牡蛎样品中添加1.0ng／g的多氯联苯标准液时，多氯联苯的回收率为81．33％～85．33％；相对标准偏差为7．33％～9．21％。方法的测定低限为0．3ng／g。另外，通过优化前处理方法，使用硅胶净化柱，缩短了样品的前处理时间，减少了试剂消耗，提高了回收率。

| Abstract: | A method for determining residues of seven kind of polychlorinated biphenyls in aquatic products was developed by gas chromatography,and analyzed in fish,shrimp,shellfish,crab,soft shell turtle,and so on.The test results showed the method was linear over the range assayed,1.0~200 ng/mL,with all correlation coefficiens>0.999.Recovery studies were performed at 1.0 ng/g level by spiked ling muscle and scallop sample,and the average recoveries ranged from 81.33% to 85.33% with a relative standard deviation betw... |
