摘　　要：为了准确评估和监测土壤中重金属的污染情况,本文采用原子荧光光谱法(AFS)测定土壤砷、汞的含量。采用微波消解处理土壤样品后,使用AFS同时测定砷、汞含量,结果表明,该检测方法具有良好的线性关系,精度和回收率也较高。土壤样品中砷、汞含量均低于GB15618—1995二级标准的限定值要求,对农作物不构成砷、汞超标的污染和危害。In order to accurately assess and monitor the pollution of heavy metals in soil,the atomic fluorescence spectroscopy(AFS)is used to determine the arsenic and mercury content in soil in this paper.After using microwave digestion to treat soil samples,the As,Hg contents are measured using AFS simultaneously,and the results show that the detection method have a good linear relationship,and the accuracy and recovery rate are also good.The content of As,Hg in soil samples are lower than the limit value requirements of GB15618—1995 secondary standards,and it does not constitute As,Hg pollution and hazards to crops.
