The rH Index For Quality and Environmental Controls: Standards and Application Procedures

摘要

The quantity rH, an index of the reducing power of a redox system is, in conceputal and operational terms, coordinatively linked with the two familiar electro-analytical quantites: redox potential (E_O/R) and pH, and has recently become important in quality and environmental controls (hyrographic network, human consumption waters, industrial effluents, etc.). It has some signficant problems of standardization and methodological applications, especially on passing from pure water medium to aqueous-organic media, and the results of the most recent researches are here presented.
