Application of Orp for the Evaluation of Water Contamination

Abstract

Water pollution characterization consumes a lot time, facilities and materials. Application of easy applicable and accurate method for pollution determination is quiet actual still now. Redox reactions in water are usually biologically mediated and therefore, the oxidation reduction potential (ORP) of wastewater and groundwater systems depends upon biodegradation processes. Oxidation and reduction reactions control the behaviour of many chemical constituents in the water. The determination of ORP is advisable in water that contains a relatively high concentration of a redox-active species, e.g., organic carbon, the salts of many metals (Fe²⁺, Mn²⁺) and strong oxidising (chlorine, oxygen) and reducing (sulfite ion) agents. Water pollution characterization upon ORP and different types of polluted water was investigated. The main outcome of this research – ORP can be used as easy applicable measurement for different types of water as pollution indicator.
