在电弧粉末法光谱分析中,经常采用卤化反应来加速某些元素的蒸发速度。但是如何取得最充分的卤化反应效率,是很值得研究的课题。在以往的工作中,对卤化剂及电极形状方面考虑较多,如用加罩电极,双电弧电极,深孔电极,杯形电极等,然后把卤化物或卤化物与其它物质混合物直接加入到样品中装入电极,待其在热电弧中起卤化反应,使某些元素分馏蒸发,降低被测元素检
In arc powder spectroscopy, halogenation reactions are often used to accelerate the evaporation rate of certain elements. However, how to obtain the fullest halogenation reaction efficiency is a topic worth studying. In the past work, more consideration has been given to the shape of the halogenating agent and the electrode. For example, a capped electrode, a double arc electrode, a deep-hole electrode, a cup-shaped electrode and the like are used. Then, a mixture of halide or halide and other substances is directly added to Sample into the electrode, to be in the heat of the arc from the halogenation reaction, the evaporation of some elements of distillation, reducing the elemental detection
