摘要
循环水中的钾离子测定可采用火焰光度法。由于循环水中存在的钠、钙、镁等其他金属离子对测定有一定的干扰,因此,在测定过程中采用对比的方法,在制作标准曲线时加入干扰大的镁离子做本底液,再对每种干扰离子进行比对试验,即可从试验结果找出最佳的测定条件。
Potassium ion in the circulate water could be determined by flame photometry method, but metal ions in the circulate water such as sodium, calcium and magnesium could cause certain jamming on the potassium ion determination, and the comparison method was adoptedl Drawing of the standard curve with the reference liquid added by big jamming magnesium ion, comparison experiments were made by each jamming metal ion, and the best optimum test conditions were found from the experiments results.
