Determination of Semi-Volatile Organic Compounds in River Water near Leptomitus lacteus Growth Locations by SPE-GC-MS/SIM Method

  • 摘要: 为测定水节霉发生地河水中ρ(SVOCs)(SVOCs为半挥发性有机物),比较了LLE(液液萃取)和SPE(固相萃取)前处理法提取加标空白水样中ρ(SVOCs)的GC-MS/SIM测定结果,确定并采用重现性好的SPE-GC-MS/SIM法测定了水节霉发生地河水中的ρ(SVOCs). 结果表明,LLE和SPE法对SVOCs的加标回收率分别为41.8%~121.5%和31.5%~124.4%,相对标准偏差分别为6.0%~18.0%和0.9%~14.5%,二者回收率相差不大,但SPE法的相对标准偏差小于LLE法,SPE法重现性较好,因此采用SPE-GC-MS/SIM法测定2011年2月水节霉发生地河水中的ρ(SVOCs),共检出29种SVOCs,其中ρ(邻苯二甲酸二乙酯)、ρ(∑PAHs)、ρ(硝基苯)、ρ(1,2-二氯苯)和ρ(1,4-二氯苯)分别为1 020.59、532.14、43.39、38.52和19.57 ng/L,均未超出GB 5749—2006《生活饮用水卫生标准》相关限值,表明水节霉发生地未发生SVOCs污染.
