摘要
利用固相萃取法提取变压器油中的多氯联苯,采用浓硫酸净化、气相色谱法进行分析,根据峰型和保留时间,以多氯联苯的商业用混合物的形式进行定性、定量,可以定量检出变压器油中2mg/kg以下的多氯联苯。
SPE extraction was applied to extract the PCB in transformer oil, PCBs was determined by means of the gas chromatography after sulfuric acid cleanup. The identification and quantitation of PCBs residues as Aroclors were accomplished by comparison of peak pattern and retention time of the most similar Aroclor standard. The method detection limits were 2 mg/kg.
