摘要
采用加压流体萃取-固相萃取-气质联用法测定土壤中苯胺,选择硅藻土为分散剂,二氯甲烷/丙酮(1:1)混合溶剂洗脱剂,建立一种快速、准确测定土壤中苯胺的方法。结果表明:苯胺的线性范围为0.1~5 mg/L,相关系数为0.999 8,两个浓度下方法平均回收率52.2%~60.6%,相对标准偏差(n=6)为4.48%~5.76%,方法检出限为0.03 mg/kg。
A rapid and accurate method for the determination of aniline in soil was established by using pressure fluid extractionsolid phase extraction-GMS.Diatomite was selected as dispersant and methylene chloride/acetone(1:1)mixed solvent eluent.The results showed that the linear range of aniline was 0.1-5 mg/L,the correlation coefficient was 0.9998,the average recoveries were 52.2%~60.6%,the relative standard deviations(n=6)were 4.48%~5.76%,and the detection limit was 0.03 mg/kg.
