Polarizing electrode needs submergence in the seawater when using, and the chloride ion in sea water occurs oxidoreduction anti-with the electrolyte in electrode
Should, and then by the ocean potential value at preamplifier detecting electrode.But this unpolarizable electrode is deposited in actual use
In some problems：(1) unpolarizable electrode obtains the electric field potential of present position by the redox reaction of ion, unavoidably
Electrochemistry noise is carried out in area, causes electrode self noise level to be difficult to reduce further；(2) unpolarizable electrode operationally needs one
Fix time and reach electrochemical equilibrium it is impossible to quickly be measured；(3) redox reaction of ion will lead to electrode itself not
Break and be consumed.
A kind of gma electrode of new type is suggested in the recent period, this electrode be made up of chemically inert valve metal (as tantalum, titanium,
Niobium etc.), electrode surface has one layer of uniform, fine and close metal oxide layer.This electrode has loose structure, by capacity coupled
Mode Measuring Oceanic potential value, thus also it is referred to as capacitance electrode.Due to capacitance electrode for chemical inertness electrode it is extremely difficult to sea
There is redox reaction in ion in water, can avoid the generation of electrochemistry noise, itself also will not in use by
Consume.Known according to the operation principle of unpolarizable electrode, unpolarizable electrode limits in use environment and is necessarily required to certain density chlorine
Ion, and capacitance electrode has no particular requirement to the ionic type in use environment, therefore not only can be applied to marine environment,
It is readily adaptable for use in the environment such as rivers, lake, the waters even polluted by heavy metal ion.These advantages of capacitance electrode are permissible
Make it have more being widely applied property.
Utility model content
