摘　　要：本研究使用石墨炉原子吸收光度法,在3种不同的浸出方法(水平振荡法、硫酸硝酸法、乙酸法)条件下,对土壤中的重金属铅进行了测定。各种浸出方法的结果表明,在达到检测标准要求的同时,均能得出标准曲线、加标回收率和检出限。土壤修复后,乙酸法浸出是一种可用于铅检测的合适浸出方法,且检出水平高。In this study,the heavy metal lead in soil was determined by graphite furnace atomic absorption spectrophotometry under three different leaching methods(horizontal oscillation method,sulfuric acid-nitric acid method and acetic acid method).The results of various leaching methods show that the standard curve,recovery rate and detection limit can be obtained at the same time.After soil remediation,acetic acid leaching is a suitable leaching method for the detection of lead,which can detect the highest concentration.
