中文摘要:

      为了禁止含砷、汞、铅物质应用到烟花爆竹药物中,建立ICP-AES方法,在烟花爆竹药物经乙醇、丙酮及硝酸处理后,选用As 189.042 nm、Hg 194.227 nm、Pb 220.353 nm分析线同时测定这3种元素的含量,结果:相对标准偏差为1.97%~2.71%,回收率为98.5%~101%. 方法操作简单快速,检出限低、干扰小,结果准确可靠.

英文摘要:

      In order to ban the use of arsenides,mercurides and lead compounds in pyrotechnic compositions,the amounts of As, Hg and Pb were simultaneously determined by ICP-AES at wavelengths 189.042, 194.227, 220.353 nm respectively,after these were pretreated by alcohol, acetone and nitric acid. The average recoveries were 98.5%~101% with relative standard deviations of 1.97%~2.71%. The method has the merits of convenient operation, rapid, low detection limit, few interference and reliable results.
