本文研究了利用时钟反应S_2O_8~(2-)+(?)(1%淀粉作指示剂)分析Fe~(3+)、Fe~(2+)离子浓度;H_2O_2+(?)(1%淀粉作指示剂)分析WO_4~(2-)、Cr_2O_7~(2-)、VO_3~-离子浓度;BrO_3~-+(?)(偶氮洋红作指示剂)分析苯酚、α-萘酚浓度,并作出这些离子的工作曲线。
In this paper, we analyzed the concentration of Fe ~ (3 +) and Fe ~ (2+) ions using the clock reaction of S_2O_8 ~ (2 -) + (? (2 -), Cr 2 O 7 ~ (2 -) and VO 3 ~ - ion concentration were analyzed by using BrO_3 ~ + (?) As an indicator The working curve of these ions.
