摘　　要：采用原子吸收光谱法(AAS)、电感耦合等离子体发射光谱法(ICP-AES)分别测定水中的钾、钠、钙、镁含量,对检出限、精密度、准确度和加标回收率等指标作比对。通过对比发现,2种方法均能满足质量控制的要求,测定结果之间无显著性差异;与AAS法相比,ICP-AES法操作更简单,并可实现多元素的同时分析。The potassium,sodium,calcium and magnesium were measured by (AAS)atomic absorption spectroscopy and inductively coupled plasma emission spectroscopy(ICP-AES),and the detection limit,precision,accuracy and calibration recovery rate were compared.By comparison,both two methods can meet the requirements of quality control and have no significant difference between measurement results;compared with AAS method,ICP-AES method is simpler and can realize simultaneous analysis of multiple elements.
