| 摘 要： | 溶液中加入氧化剂（高锰酸钾），氧化电极表面的金属铜形成铜离子进入溶液中，金属氧化溶出时间与溶液中的金属离子的浓度成正比，峰值与溶出时间成正比，因此峰高与溶液中金属离子浓度成正比，以此测定溶液中铜离子的浓度。

| Abstract: | Putting divalent Hg ion in the Cu ion solution, the Cu ion and Hg ion are reduced together by electrolysis and form mercury alloy, concentrating on the electrode of Hg film. Then, putting the oxidizer （potassium permanganate） in the solution, the Cu metal on the electrode surface is oxidized, which becomes Cu ion and enters the solution. The oxidation and solution time of metal is in direct proportion to the concentration of metal ion in the solution. The peak value is in direct proportion to the solution time. Therefore, the peak height is in direct proportion to the concentration of metal ion in the solution, which can determine the concentration of Cu ion in the solution. |
