electrogravimetry
Quick Summary
Electrogravimetry is a quantitative chemical analysis technique that uses an electric current to deposit a solid substance onto an electrode from a solution. This deposited solid is then weighed to determine the concentration of the analyte in the original sample.12
This method is a type of gravimetric analysis, where the constituent being analyzed is converted into a weighable substance. In electrogravimetry, the analyte undergoes an electrochemical reaction at the electrode, forming a solid deposit. This process can be performed using either a constant current or a constant potential, with constant potential offering greater selectivity but taking longer. Electrogravimetry can also be used to remove interfering substances from a sample before analysis.12
