Popis: | Enthalpies of Cl– anion exchange for anions of nicotinic, isonicotinic, dipicolinic, and cinchomeronic acids on the strongly basic anionite AV-17-8 are measured at 298 K by means of microcalorimetry. Partial and standard enthalpies of sorption of pyridinecarboxylic acid anions on the Cl-form of AV-17-8 anionite from aqueous solutions are determined. The values of standard enthalpies lie in the range 3–14 kJ/mol, increasing in the order nicotinate, isonicotinate, dipicolinic acid anions, and cinchomeronic acid anions. |
