| 摘 要： | 建立一种快速溶剂萃取(ASE)-凝胶净化(GPC)-高效液相色谱(HPLC)法测定土壤中6种邻苯二甲酸酯(PAEs)的方法。土壤样品经二氯甲烷-丙酮(体积比为1∶1)快速溶剂萃取后,过Bio-Beads SX-3凝胶层析柱净化,收集12~28 min的GPC洗脱液,并进行HPLC-DAD检测分析。通过分段收集,消除了土壤中共存的16种多环芳烃在225 nm紫外波长下对6种PAEs测定的干扰。采用ZORBAX Eclipse Plus C_(18)(150×4.6 mm,5μm)反相色谱柱,以乙腈-水为流动相进行梯度洗脱,流速为1 mL/min。结果表明,6种PAEs的线性关系良好,相关系数大于0.999 9,方法检出限为2.7~11.5μg/kg,精密度的相对标准偏差为1.5%~9.5%,加标回收率为66.5%~102%。该方法适用于含多环芳烃的土壤中PAEs的准确测定。
