采用王水溶样,ICP-AES法同时测定烟火药剂中的铅、铬、铋元素的含量。对烟火药剂样品消解方法、方法的检出限、分析波长、精密度、回收率等进行了实验。结果显示其相对标准偏差均在5%以下,回收率在86.2%~102.2%之间。运用该方法对不同烟火药剂进行检测,测定结果与AAS单元素分析结果吻合。 Simultaneous determination of lead, chromium and bismuth in pyrotechnics by ICP-AES using aqua regia sample. The pyrotechnics sample digestion method, the detection limit of the method, analysis of wavelength, precision, recovery rate were tested. The results showed that the relative standard deviations were below 5% and the recoveries were between 86.2% and 102.2%. Using this method, different pyrotechnics were tested, and the results were in good agreement with those of AAS.
