First Claim
Patent Images
1. A method to measure concentration of metal ions in presence of one or more organic compounds in an aqueous medium comprising:
- contacting an aqueous medium comprising metal ions and one or more organic compounds with an ultramicroelectrode (UME) in a UME cell;
cleaning surface of the UME from deposition of the one or more organic compounds by passing a gas on the surface of UME, by forming a gas on the surface of UME, by mechanically cleaning the surface of UME, or combinations thereof;
subjecting the UME to a set Y of one or more potential cycles causing oxidation of the metal ions in lower oxidation state to a higher oxidation state or causing reduction of the metal ions in higher oxidation state to a lower oxidation state; and
measuring a steady state current thereby measuring the concentration of the metal ions.
