| 摘 要： | 用HNO3-HCl溶解试样,在几个相同量的试液中,分别加入质量浓度依次递增的5种元素的标准溶液,用火焰原子吸收法连续测定了Fe、Pb、Sb、Zn和Ni的含量,建立了优化的仪器测定条件,并对可能存在的元素进行了干扰试验。结果表明,Fe、Pb、Sb等5种元素的回收率为98.0%～102.3%,相对标准偏差为1.4%～2.5%。

| Abstract: | After dissolved by nitric acid and hydrochloric acid, several same samples were added into the five element standard solutions increased by concentration degrees,respectively,then the contents of iron,lead,stibium,zinc and nickel were determined successively by fire atomic absorption spectrometry(FAAS).The optimum determination conditions have been established.The interferential tests for other elements that probably exist have been conducted.The rate of recovery is 98.0%~102.3%,the relative standard deviation is 1.4%~2.5%. |
