摘要
本文利用高效液相色谱法测定水中痕量多环芳烃(PAHs)以二氯甲烷作溶剂,超声提取水中痕量PAHs;甲醇、水作流动相,梯度淋洗,用程序可变波长荧光检测器测定PAHs浓度为0.007-06μg·ml^(-1)范围时,线性相关系数均在0.9999以上;峰高、峰面积的相对标准偏差(n=10)分别为1.01-1.85%,2.00-3.94%;检测限(S/N=2)为3.1-23.0pg;实际水样的加标回收率为90.1-98.6%
A method of the quantitation of trace polycyclic aromatic hydrocarbons(PAHs) in water by high performance liquid chromatography (HPLC) with fluorometric detection and programmed excitation and emission wavelength pairs is proposed.The mobile phase is a linear gradient of methanol-water. The relative standard deviations of peak height and peak area are in the range 1.01-1.85%, 2.00-3.94%, respectively at PAHs concentration levels of 0.007-0.6μg·nol-1. The detect limits (S/N=2) are 3.1-23.0pg.The proposed method was successfully applied to quantify seven PAHs in water. The recoveries of PAHs from water were 90.1-98.6% . This highly sensitive auto-made HPLC analysis for trace PAHs in water can be applied to water survey.
