Abstract
Koloidi su disperzni sustavi s veličinom čestica od 1 do 100 nm. Dijele se obzirom na agregatno stanje i veličinu čestica disperzne faze, s obzirom na solvataciju, povratnost koagulacije itd. Koloidni sustavi pokazuju tzv. Tyndallov efekt. Osim toga, čestice koloida se gibaju, njihovo gibanje nazvano je Brownovo gibanje, imaju i naboj što utječe na električna svojstva koloida. O električnim svojstvima čestica koloida ovisi stabilnost koloida koja se definira kao sposobnost čestica koloida da ostanu u raspršenom (disperznom stanju) bez taloženja. Elektrokinetički ili zeta potencijal je naboj koji se javlja na granici difuznog sloja čestice koloida i njime se može pratiti stabilnost ili destabilizacija koloida. Cilj ovog rada bio je objasniti elektrokinetički ili zeta potencijal, njegovo značenje i utjecaj na stabilnost koloida.

Parallel abstract (English)
Disperse systems whose particle size ranges from 1 to 100 nm are known as colloid systems. They are grouped according to their physical form and particle size, solvatation, coagulation reversibility etc. Colloidal fundamental properties explained in this paper include Tyndall effect, as an optical charasteric, Brown's motion and properties arising from their electrical charge and colloid stability problematic, which is determined with the value of zeta potential. It is the potential difference that occurs on the border of the diffuse layer and most common method for zeta potential measurement is electrophoresis.
