WebJun 1, 2024 · The oxidation-reduction potential is a measure of the degree of oxidation/reduction of materials. The ORP value in this study indicates the amount of injected or residual chlorine during the usual reaction period (ASTM, 2014b ). The amount of injected chlorine was measured by an online ORP meter (JUMO brand) every 2 h (in mV). WebOxidation-reduction potential is the potential (voltage) at which oxidation occurs at the anode (positive) and reduction occurs at the cathode (negative) of an electrochemical cell. In simple terms, from a microbial perspective, an oxidizing chemical pulls electrons away from the cell membrane, causing it to become desta- bilized and leaky.

WebWhat is ORP? Oxidation reduction potential (ORP), also known as REDOX, is a measurement that reflects the ability of a molecule to oxidize or reduce another molecule: Oxidation is the loss of electrons, so oxidizers accept electrons from other molecules. Reduction is the gain of electrons, so reducers donate electrons to other molecules.
