Free energies of transfer of anions from water to cationic micelles from ionic exchange measurements

摘要: Ionic exchanges for several anions in hexadecyltrimethylammonium (CTA) have been measured by ultrafiltration and the shift concentration of ferric thiocyanate complex CTA addition. The results are compared with those previously reported using an absorbance method. agreement between 3 methods is good, they allow calculation free energies transfer from water to micelles studied. values discussed terms properties anions. It concluded that both entropic enthalpic effects responsible specificity binding micelles. 18 references.
