Zeta Potential - property of an electric structure that is usually built up at interfaces
Zeta potential is a parameter characterizing electrochemical balance on connections. It relies on the
qualities of fluid as well as on qualities of the outer lining area. It performs an important part
theoretically of aggregative balance - DLVO concept [1,2]. Electrostatic repulsion between contaminants
relies on the value of zeta prospective. The higher the zeta prospective, the more powerful the
repulsion, the more constant the system becomes. For instance, high zeta prospective of the fat drops in
dairy stops them against coalescence. Reduction of it due to addition of acid would lead to dairy
products development from coalescence drops.
Zeta prospective is a property of a powered framework that is usually built up at interfaces: Dual Part.
According to Basic principles of Colloid and Program Science by J. Lyklema : "...the reason for the
development of a "relaxed" ("equilibrium") double layer is the non-electric appreciation of charge-
determining ions for a surface...". This process leads to the build up of an "electric surface charge". This
surface cost makes an electrostatic area that then impacts the ions in the large of the fluid. This
electrostatic area, along with the heat motion of the ions, makes a countercharge, and thus displays the
electrical powered surface cost. The net power cost in this testing soften layer is equal in scale to the net
surface cost, but has the opposite polarity. As a result the complete framework is electronically fairly
Electric potential decays almost exponentially, which allows introduction "Debye length" as estimate of
the DL thickness. Electric potential drops by approximately 2.7 times at the distance from the surface
that equals to the Debye length. Debye length depends mostly on an "ionic strength". It is approximately
1 nm at the ionic strength 0.1 M, and it increases as a reciprocal square root of the ionic strength
(electrolyte concentration), becoming, for instance, 10 nm at the ionic strength 0.001 M.
