Electrogravimetry

Japanese: electrogravimetry
Electrogravimetry

...Broadly speaking, there are methods such as electrolysis, which use electrodes with a large surface area in a well-stirred solution to quantitatively complete electrolysis, such as electrogravimetry and coulometric analysis, and methods such as polarography and chronopotentiometry, which use small electrodes in a stationary solution to observe the electrolysis phenomenon that occurs only near the electrode surface.
[Electrogravimetry]
A method of analysis in which metal ions in a solution are reduced by electrolysis, quantitatively depositing them on a cathode, and the mass of the deposited metal is measured. When two or more metals coexist, a controlled potential electrolysis method is used in which the cathode potential is limited to a potential at which only the target metal is deposited.

…大別すると,電解重量分析や電量分析のように表面積の大きな電極を使って,十分かくはん(攪拌)した溶液中で,電解を定量的に完結させる方法と,ポーラログラフィーやクロノポテンシオメトリーのように微小電極を用いて静止溶液中で,電極表面近傍だけで起こる電解現象を観察する方法とがある。
[電解重量分析electrogravimetry]
 電解により溶液中の金属イオンを還元して陰極上に定量的に析出させ,その析出金属の質量を測定して分析する方法。2種以上の金属が共存する場合には,陰極電位を目的金属のみが析出するような電位に限定して電解する定電位電解法が用いられる。…
