Abstract
Methods for in situ measurement of an oxidation reduction potential (ORP) and pH of a solution comprising iron are provided. The methods comprise measuring a kinetic parameter at an electrode surface of an electrode system comprising a working electrode, a counter electrode and a pseudo-reference electrode, wherein the kinetic parameter is associated with ferric reduction or both ferric reduction and ferrous oxidation and comparing the kinetic parameter to calibration data for the electrode system to determine the ORP and pH of the solution. Also provided are apparatus and systems for in situ measurement of an ORP and pH of a solution comprising iron. The apparatus and systems comprise an electrode system comprising a working electrode, a counter electrode and a pseudo-reference electrode and a detector for measuring a kinetic parameter at an electrode surface of the electrode system.
