The adsorption in high-dispersed CdTe systems containing medium-modifiers has been studied. As modifying substances, anionic phosphorous-containing organic compounds were selected. An analysis of the effect of the molecular structure of the disperse medium on the adhesion energy in disperse medium–CdTe systems was carried out. Introduction of phosphorus-containing modifiers into high-dispersed aqueous– and alcohol–CdTe systems produces a change of their characteristics, due to the formation of a monomolecular adsorption layer on the surface of particles of the disperse phase. By selecting appropriate compositions of the disperse medium modifier one can produce a purposeful effect on the stability of high-dispersed CdTe systems.
