摘要
参照美国ＥＰＡＳＷ８４６规定的标准方法，采用Ｑ－４５型微波溶样系统消解样品，原子吸收法测定铁路桃浦危险品货站固体废渣原样、浸滤渣样、浸提液样中的重金属Ｂｅ、Ｃｄ、Ｃｒ、Ｃｕ、Ｎｉ、Ｐｂ、Ｚｎ。研究了样品的消解条件、分析的最佳条件。各元素精密度实验的相对标准偏差在０．５４％～１２．８％，标准土样的测定回收率在７６．４９％～１０３．３３％。并报告了对上海铁路局桃浦危货站现场样品的测定结果。
Refer to standard method of U.S.EPA SW 846,Be Cd Cr Cu Ni Pb Zn in solid wastes of hazardous goods in the field of railway station are determined by using Q 45 microwave digestion system and AAS. Microwave acid digestion technique and analysis conditions are studied. Standard deviation is 0.54%～12.8%. Rate of recovery is 74 49%～103 33%.
