辽宁石油大学研究了以二甲亚砜作为萃取溶剂的样品预处理方法和高效液相色谱(HPLC)相结合以测定环保型橡胶填充油中多环芳烃的方法。优化了溶剂萃取环保型橡胶填充油多环芳烃和HPLC测定其组成的条件。结果表明,二甲亚砜萃取多环芳烃的最适宜萃取温度为21～25℃,萃取重复性最大偏差值为0.27个单位,标准偏差为0.190个单位。萃取回收率最低90.1%。最高109.8%;HPLC分析以ZORBAXPAH色谱
Liaoning University of Petroleum, Dalian, Liaoning Province, China Abstract A method for the determination of polycyclic aromatic hydrocarbons (PAHs) in environment-friendly rubber-filled oils by means of a combination of sample pretreatment with dimethyl sulfoxide as extraction solvent and high performance liquid chromatography (HPLC) Optimization of the solvent extraction environment-friendly rubber filled polycyclic aromatic hydrocarbons and HPLC determination of the composition of the conditions. The results showed that the optimal extraction temperature for dimethyl sulfoxide extraction of polycyclic aromatic hydrocarbons was 21 ~ 25 ℃, the maximum deviation of extraction reproducibility was 0.27 units with a standard deviation of 0.190 units. Extraction recovery of 90.1% minimum. The highest 109.8%; HPLC analysis ZORBAXPAH chromatography
