摘要：本文利用原子吸收分法分别用钾空心阴极灯测钠、锌空心阴极灯测铜，目前未见相关文献提出钾空心阴极灯测钠。结果：标准曲线线性均良好，相关系数均在0.999以上。RSD在0.47%-0.53%之间，回收率在99.1%-102%之间。钾灯测钠、锌灯测铜质控样结果均合格，一灯多用在环境监测工作中是可行的。
Abstract: in this paper, using the method of atomic absorption points respectively with hollow cathode lamp sodium, potassium zinc copper hollow cathode lamp test, at present did not see related literature potassium sodium hollow cathode lamp test is put forward. Results: the standard curve linear good, correlation coefficients of above 0.999. RSD between 0.47% and 0.53%, recovery is between 99.1% and 102%. Copper zinc potassium sodium lamp test, lamp test sample results are qualified, one light multi-purpose is feasible in the environmental monitoring work.
