摘要:
利用快速溶剂萃取-气相色谱-质谱法对建设用地土壤中11种半挥发性有机物(SVOCs)进行分析,并优化了萃取溶剂、温度和循环次数。经测定,标准曲线的相关系数(R2)>0.990,相对标准偏差(RSD)为1.7%~14%,加标回收率为65.0%~86.4%,方法检出限为0.01~0.06 mg/kg。结果表明,方法的精密度、准确度、灵敏度均能满足建设用地土壤中11种SVOCs的分析要求。

Determination of 11 Semi volatile Organic Compounds in the Soil of Construction Land
FENG Xiao-kang,ZHENG Ya-li
Abstract:
Accelerate solvent extraction gas chromatography mass spectrometry was used to analyze 11 semi volatile organic compounds in the soil of construction land. The extraction solvent, temperature and cycle times were optimized. The results showed that the correlation coefficient of the calibration curve (R2) is>0.990, the relative standard deviation (RSD) ranged from 1.7%~14%, the recovery rates were in the range of 65.0%~86.4%, and the detection limits of the method were 0.01~0.06 mg/kg. The precision, accuracy and sensitivity of this method can meet the analysis demands of the above mentioned 11 organic pollutants in the soil of construction land.
