Description
Abstract
In this research work comparative analysis of four different surfactants has been given. The identification of these products has been made by IR- and UV- spectroscopy. The physical and chemical properties of the formed surfactants including interfacial tension and specific electroconductivities have been determined. From these measurements, the maximum surface excess concentration and the minimum area of the molecule at the water /air interface, the surface pressure, the standard thermodynamic parameters of adsorbtion and micellization have been calculated. Moreover, petrocollecting and petrodispersing properties of these substances have been measured and maximum values of petrocollecting coefficients have been determined. Some correlations between these parameters of the synthesized surfactants and their ability to collect thin petroleum films from the water surface have been obtained.
