摘　　要：本文提供了金属固体样品的流动在线电解方法。电解得到的样品溶液可以直接送往原子光谱仪器进行检测。研究了电解条件对信号峰的影响,并对铝合金样品中的少量镁进行了在线电解—火焰原子吸收及ICP-原子发射光谱测定。方法快速简便,每个样品的分析工作可在数分钟内完成。A flow-injection system Was developed in which alloy metal samples are electrolytically dissolved and the dissolved samples are analyzed by flame atomic absorption spectrometry and ICP-atomic emission spectrometry. Electrolyte solutions consisting of 0.4-2.0mol/L. nitric acid are better for both dissolution and determination The signal peak absorption increases linearly with the electrolysis time or current within a certain range. The reproducibility of electrolysis and determination is about 3% to 5%.
