酒中金属元素的测定对酒的质量控制,食品卫生等甚为重要,对汽油酒精混合燃料也要控制金属元素的含量。因而寻找一个灵敏、准确、快速又能同时测定乙醇溶液中多种元素的分析方法具有一定的重要意义。文献曾报导过用各种方法测定酒中的金属元素。例如电化学法,分光光度法,原子吸收法,火焰发射光谱法等。近年来又有用ICP发射光谱法的。但是将乙醇或乙醇含量高的溶液喷入等离子体时会遇到一些困难。另外,由于乙醇对ICP
Determination of the metal elements in the wine quality control, food hygiene is very important, but also to control the blending of gasoline and alcohol fuel metal content. Therefore, it is of great importance to find a sensitive, accurate, rapid and simultaneous method for the determination of multiple elements in ethanol solution. The literature has reported the determination of metallic elements in wine by various methods. Such as electrochemical method, spectrophotometry, atomic absorption method, flame emission spectrometry and the like. In recent years, another useful ICP emission spectrometry. However, there is some difficulty in injecting a solution of high ethanol or ethanol into the plasma. In addition, due to ethanol on ICP
