Abstract
separate molecular and ionic impurities from aqueous streams. In the recent communication, semi-equilibrium dialysis (SED) technique is used to separate 1-, 2- Naphthols (1-, 2- Naph.OH), 1-, 2- Naphthoic acids (1-, 2- Naph.A) and 1-, 2- Naphthyl acetic acid (1-, 2- Naph.A.A) from aqueous streams by aqueous surfactant solution (Cetyl pyridinium chloride CPC). The solubilisation equilibrium constant K in case of polar solutes are related to the mole fraction of organic in micelles (Xorg) by the relation k= ko(1-bXorg)2 , ko is the value of the solubilisation constant as Xorg approach zero. From the obtained results of the solubilisation constants K for the recent organic pollutants, one can concludes that inserting a phenyl ring as well as other groups to the parent compound (benzene) accompanied by increasing the solubilisation constantK. The activity coefficients of both organic pollutant and surfactant were also calculated.
