Paper Title:
The Effect of Seawater Salinity on the Equilibrium Time of Oxidation Reduction Potential
  Abstract

On the basis of a large number of continuous monitoring experiments for the five-line salinity of seawater, and the uncertainty of natural seawater oxidation reduction potential (ORP) is 2.2mV, the effect of seawater salinity on the equilibrium time of ORP is studied qualitatively and quantitatively. The results indicated that the greater the salinity, the longer the time of reaching to ORP equilibrium value, the longer the equilibrium time of the seawater ORP value. It is showed that the ORP equilibrium value was obtained at 30minutes, 90minutes, 120minutes, 240minutes and 300minutes from seawater with salinity as 5,20,30,35 and 40, respectively, and the equilibrium time was more than 12 hours. Accuracy and stability of the equilibrium time of seawater ORP value under different salinity can provide technical support for metrological verification of ORP sensor.
