Conductometric Study of the Interaction of Insecticide Profenofos with Cationic and Anionic Surfactants in Aqueous Medium
Journal Title: International Research Journal of Pure and Applied Chemistry - Year 2017, Vol 15, Issue 1
Abstract
This work aims is to find means to improve the solubility of the not very water soluble organic pollutants. For that, we made a study of solubilization of a not very water soluble organophosphorus insecticide, and in weak concentrations in the ionic micellar systems, in the presence of active surface CTAC and SDS. With an aim of better understanding this mechanism of solubilization of insecticide profenofos (PFF). Concentration effect of PFF and temperature on the CMC have been studied by conductometric way and the determination of the thermodynamic parameters of micelization. It was noted in this work that the CMC and the values of the degree of electrolytic dissociation of surfactant used decrease with the effect PFF concentration in solution and according to the temperature of the medium. The results of this study showed on the one hand that the Gibbs free enthalpy (∆G°) of the reactions of association between the PFF and the active surface ones is negative and believes in absolute value. In addition the calculation of the degrees of dissociation showed that the PFF is solubilized in these active surface ionic.
