【摘要】 采用索氏提取-气相色谱法测定土壤中的五氯酚,优化了试验条件。方法在0μg/kg~200μg/kg范围内线性良好,检出限为0.03μg/kg,空白土壤加标样测定的RSD为2.6%,回收率为95.4%~101%。更多还原

【Abstract】 The pentachlorophenol in soils was determined by GC with Soxhlet extraction.The experimental conditions were optimized to produce the following results: good linearity in the range from 0 μg/kg to 200 μg/kg,the detection limits 0.03 μg/kg,the RSDs of the blank soils added standard samples 2.6%,and the recoveries from 95.4% to 101%.更多还原
