摘　　要：采用电感耦合等离子体发射光谱法(ICP-OES)和原子吸收光谱法(AAS),分别测定了水质标准质控样和铬污染场地的地下水中钾、钠、钙、镁的含量,对检出限、精密度、准确度等指标进行了比对。结果表明,2种方法的测定结果无显著差异,均能满足实验室的质控要求。相比AAS法,ICP-OES法无需进行样品稀释和换灯,操作更简单,并可同时测定多种元素。The contents of potassium,sodium,calcium and magnesium in standard water quality control samples and groundwater from chromium contaminated sites were determined by inductively coupled plasma emission spectrometry(ICP-OES)and atomic absorption spectroscopy acid(AAS),respectively.The detection limit,precision and accuracy were compared.The results showed that there was no significant difference between the two methods,and both methods could meet the requirements of quality control in the laboratory,Compared to AAS method,ICP-OES method did not required sample dilution and lamp switching,and the operation was simpler.It could also simultaneously determine multiple elements.
