矿石极谱分析经常遇到共生元素的干扰问题,表现为氧波、叠波、前波、氢波等干扰。为使分析工作顺利完成需选择适当的底液和采用有效的隐蔽和分离手段。在极谱分析中一种组分的隐蔽可以理解为通过一种附加物(隐蔽剂)与它产生化学上的结合或对其电极过程的影响,使得在另一组分进行极谱测定时不再产生干扰的极谱波。由于用隐蔽能简便地除去或暂时抑制体系内不需要成分的影响,无需依赖物理的分离
Ore polarographic analysis often encounter the interference of symbiotic elements, manifested as oxygen waves, stacked waves, the former wave, hydrogen waves and other interference. For the successful completion of the analysis need to select the appropriate base fluid and the use of effective means of concealment and separation. The concealment of a component in polarographic analysis can be understood as the chemical binding to it or the effect on its electrode process by an additive (occulting agent), so that when the other component is subjected to polarographic determination Reproduction of interference polarographic wave. Due to the concealment can easily remove or temporarily suppress the system does not require the impact of ingredients, without having to rely on physical separation
