constant-current electrogravimetry
Quick Summary
Constant-current electrogravimetry is an instrumental method of chemical analysis used for quantitative analysis. It is a type of electroanalysis where a solid product of an analyte's electrochemical reaction is deposited onto a preweighed electrode. The electrode is then removed, cleaned, dried, and weighed. The increase in mass directly corresponds to the amount of analyte present in the solution.1
This method is faster than constant-potential electrogravimetry, typically taking about 30 minutes per assay. However, it is more susceptible to interferences. Constant-current electrogravimetry is preferred when only one component in the solution can react to form a deposit on the electrode.1
