| 摘 要： | 在常规火焰原子吸收分光光度计上采用特制的不锈钢原子化管对碱金属元素进行无火焰原子化法测定,克服了碱金属元素在火焰中的电离效应,试液用量极少。测定结果的相对标准偏差小于0.3%(n=11),回收率为98.9%~99.2%。

| Abstract: | The alkali metal elements were determined by the non-flame atomization method on tradition flame atomic absoption spectrophotometer which was installed special prepared stainless steel atomizing tube.Ionization effect of the alkali metal elements was completely overcomed.Little sample solution were used.The relative standard deviation of results were less than 0.3%(n=11) for five elements,and recoveries were 98.9%~99.2%. |
