【摘要】 本文详细讨论了火焰发射法测定碱金属和碱土金属其单项元素时 ,对外来物质的影响、基体效应及非金属因素对样品测定的干扰造成的影响都作了专门的阐述。同时针对性地提出了几种行之有效的抑制办法。通过加入各种相应的释放剂和适当控制火焰本身的辐射来寻求进一步提高分析结果准确度的办法途径 ,提出了自己的独到见解。更多还原

【Abstract】 When the flame-emitting method is used to det er mine certain element of alkali metal and alkaline-earth metal,some other extern al substances will interfere in the sample-determing.This passage put forwards some efficient ways of restraining the interference.It suggests that appropriate kinds of releasing agent should be added,and the radiant energy of flame itself should be controlled so as to find out the best way to improve the accuracy of analysing更多还原
