【摘要】 本文提出一种新的电化学分析方法——挥气电位法。是一种利用多孔膜气敏电极直接响应气体物质的方法。使被测定的物质由液相中通过化学反应转变为气态物质,再用载气把它带至多孔气敏电极上产生电极反应,测量其电位的变化,是一种直接电位法。它与选择性电极法相似,而与气相色谱法也有共同之点。利用挥气电位法可以测定Hg、As、Sb、Sn、S、I和CN等等离子。更多还原

【Abstract】 A description is given of a new electrochemical method for determining micro substance in solution, which is termed pneumato-potentiometry by the authors. Some dissolved nonvolatile substance in solution is converted to a volatile species through chemical reaction. The volatile species is purged from solution with a carrier gas, and the gas stream is impinged and detected upon a porous gas-sensing electrode.更多还原
