| 摘 要： | 用王水溶解试样,在几个相同量的试液中,分别加入浓度依次递增的9种元素的标准溶液,用空气-乙炔火焰原子吸收法连续测定N i、Cu、Mn、Fe、Pb、Sb、Zn、Ca、Mg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实验.N i、Cu等9种元素的回收率为97.5%~103.0%,相对标准偏差为1.6%~2.9%.

| Abstract: | After dissolved by HCl-HNO_3,samples were added into the nine elements' standard solutions increased by concentration degrees respectively,then the contents of nickel,copper,manganese,iron,lead,antimony,zinc,calcium and magnesium were determined by air-acetylene fire atomic absorption spectrometry (FAAS).The optimum determination conditions have been established.The interference tests for other elements that probably exist have been investigated.The recovery was in the range of 97.5%~103.0%.The relative standard deviation was in the range of 1.6%~2.9% |
