Sažetak
Aqueous solutions of surface active substances have colloidal properties even at concentrations below the critical micellar concentration. A two component system made up of a cationic surfactant (n-dodecylamine nitrate) and an anionic organic dye (fluorescein), of a cationic organic dye (methylene blue) and an anionic surfactant (sodium n-dodecyl sulphate) in an aqueous medium, exhibits typical colloidal properties. the properties of a multicomponent system composed of an inorganic sol, negative silver iodide, and a two component system, show an even more complex dependence on the chemical nature and concentration of the components present, the time and conditions of ageing of the system. The tyndallometric and microelectrophoretic values of the two component system point to mutual colloidal interaction of the cationic and anionic surfactants, and to mutual flocculation of the inorganic sol and the surfactants in the multicomponent system.
