Cl-, HOCl, H+ will only change the ORP ±29.58 mV. 4. There is no specific temperature dependence shown. Temperature can affect an ORP reaction in a variety of ways, so no general ORP tempera-ture behavior can be characterized, as is the case with pH. Therefore, ORP measurements are almost never temperature compensated.

In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons when it is subjected to change by introduction of a new species. A solution with a higher (more positive) reduction potential than the new species will have a tendency to gain electrons from the new species (i.e. to be reduced by

The discharge of copper from mining, metallurgy and electronic industries in the aquatic environment can cause several problems (Alloway and Ayres, 1997). Copper is a toxic metal, causing for example the extermination of aquatic life as well as harmful biochemical effects on human beings ( Tao et al., 2011 , Martins et al., 2012 , Adhoum et al., 2004 ).
