Measuring Techniques for Oxidation- Reduction Potential in High Purity Water

The measurement of Oxidation-Reduction Potential (ORP) can be used in the water/steam cycle of a power plant to infer information about system reactions to water chemistry. While the measurement of ORP is by no means a new measurement, the high purity water of the water/steam cycle is a relatively new application for ORP. This presents a challenge since little information is available on proper...

The Oxidation-reduction Potential of the Luciferin-oxyluciferin System

The oxidation-reduction potential of the Cypridina luciferin-oxyluciferin system determined by a method of "bracketing" lies somewhere between that of anthraquinone 2-6-di Na sulfonate (E(o) (') at pH of 7.7 = -.22) which reduces luciferin, and quinhydrone (E(o) (') at pH of 7.7 = +.24), which oxidizes luciferin. Systems having an E(o) (') value between -.22 and +.24 volt neither reduce oxyluci...

The oxidation-reduction stoichiometry and potential of microsomal cytochrome.

In the preceding report (1) we have described the isolation, as an acidic protein of relatively low molecular weight, of the cytochrome component of rabbit liver microsomes. Of the various mammalian cytochromes, known from their spectra in crude preparations or intact cells, only cytochrome c has been previously isolated in a form which has permitted molecular characterization (24). Two propert...

Power Plant Chemistry Measurement Advancements: Oxidation Reduction Potential

Measurements which show the potential for corrosion of a plant’s metallurgy due to interaction with the system water have gained in importance within the last two decades. Among the most successful of these measurements are those which measure an actual potential which is based upon the oxidation/reduction reactions taking place. The measurement of Oxidation Reduction Potential (ORP) has been u...
