摘　　要：采用HNO3消解法、HNO3-双氧水消解法、HNO3-HCl O4消解法处理高含量有机物体系中镧系金属样品,用HK-8100型ICP-AES光谱仪测定消解后的镧系金属离子浓度,比较3种酸消解方法的相对误差率,发现HNO3-双氧水消解法中,10 m L样品中HNO3和双氧水用量为1 m L和2 m L时,误差率最小,消解效果最好。Methods of nitric acid digestion,nitric acid- hydrogen peroxide digestion,nitric acid- perchloric acid digestion were used to deal with samples of lanthanide metal in high organic systemsandthe concentration of lanthanide metal after digestion was measured by HK-8100-type spectrometer ICP-AES. After comparingrelative error rate of three species acid digestion method,we found that if the amount ofnitric acid and hydrogen peroxide was 1m L and 2 m L in 10 m L sample,the error rate nitric acid- hydrogen peroxide digestion method was minimal and the result of digestion was the best.
