Intercomparison of Redox determination methods on designed and near-natural aqueous systems : FP 7 EURATOM Collaborative Project "Redox Phenomena Controlling Systems" (KIT Scientific Reports ; 7572)

The outcome of the RECOSY Intercomparison Exercise (ICE), 16-20 November 2009, KIT-INE, Karlsruhe, conducted within the EURATOM FP7 framework is presented. The comparison of different redox determination methods allow to identify critical issues and provide the basis for more confidence in redox determinations relevant for nuclear waste disposal. Recommendations on redox measurements are given in the report and future activities proposed to further improve the reliability of redox measurements.
