PP-III-59The aim of this work is the study of the self-organization and physicochemicalproperties of solutions of 1 in a range of concentrations of 10 –4 – 10 –12 mol/L,establishing a relationship between the concentration dependence of the parametersnanoassociates, physicochemical properties of the solution 1 and the rate of thepurification of wastewater. It was shown that aqueous solutions of 1 are selforganizingsystem in which nanoparticles are formed. The size and zeta- potential ofnanoassociates in different intervals of a concentration of 1 are substantially different.The aggregates (50 nm) and the nanoassociates (200-100 nm) are formed in rangeof concentrations 10 –5 -10 –4 mol/L and 10 –12 -10 –6 mol/L, considerably. The differencein the parameters of nanoparticles formed in "normal" and low concentrations is themost probable cause of a change of the rate of purification process of wastewater inpresence of 1 in various ranges of concentrations.References[1].
