| 摘 要： | 采用自制微萃取瓶富集-反相高效液相色谱法同时测定海水中的萘、菲、荧蒽。实验选择DiamonsilC18(250×4.6mmi.d.,5μm)色谱柱,体积比为88∶12的甲醇-水作流动相,流速1.0mL/min,检测波长280nm,柱温30℃。最佳萃取条件:400mL水样,300μL正辛烷作萃取剂,NaCl浓度100g/L,萃取时间15min。在10～5×104μg/L范围内,萘、菲、荧蒽呈现良好线性关系(相关系数均大于0.9997)。萘、菲、荧蒽检出限分别为13.3、13.3、7.0ng/L;加标回收率分别为94.50%、94.05%、92.59%;相对标准偏差分别为1.60%、1.82%、0.90%。
