Abstract
Táto diplomová práca sa zaoberá stanovením povrchového napätia čistých roztokov aniónaktívnych, neiónogenných a amfoterných povrchovo aktívnych látok ako aj ich kombinácií s ďalšími látkami: NaCl, močovinou a tlačiarenskými záhustkami. Práca popisuje štruktúru, rozdelenie a vlastnosti jednotlivých druhov povrchovo aktívnych látok. Na základe závislosti povrchového napätia na koncentrácii je stanovená kritická micelová koncentrácia u jednotlivých roztokov. Je hodnotená závislosť povrchového napätia roztokov tenzidov na ich koncentrácii a prídavných látkach.
This Diploma thesis deals with surface tension of pure solutions of anionic, non-ionic and zwitterionic surface active agents. The property of surface tension of pure solutions was also followed in combination with another substances: NaCl, urea and printing thickener agents. Structure, differences and characteristic properties of surface active agents are described in this work. Critical micellar concentration for individual surfactant solutions is established on relation between surface tension and concentration. In the experimental part there is also evaluate relation between solution surface tension of surfactants and their concentration and additional substances.
