Abstract

Concentration dependence of sufare tension forf polyethylenglykol –water, KCl-water solutions and polyethylenglycol-water–KCl solu ions has been analysed. It found that in the solution PEG -water molecules are adsorbed on water surface to change its structure. In the system KCl water is dissociated and a-c dependence becomes typical for electrolites. As KCl joins PEG – water a coefficient of surface tension of the solution is increasingly reduced. Keywords: polyethylenglycol, sufare tension, adsorbtion, water structure, cohesia.
