Analysis of ion-association equilibrium of precipitable dipicrylaminate ion in aqueous solution by capillary zone electrophoresis.
The ion-association equilibrium of the dipicrylaminate ion (DPA(-)) was investigated in an aqueous solution with alkali metal ions and with its 18-crown-6 ether complexes as pairing cations by capillary zone electrophoresis (CZE). Although DPA(-) is precipitable with the pairing cations of K(+) and Cs(+) in a homogenous aqueous solution, a low concentration of DPA(-) below its solubility suppre...
متن کاملThermodynamics of Non-Ideality and Ion-Association in Saturated Aqueous Solution of Barium Nitrate at 25° C
Using Solvent Evaporating and Atomic Emission Spectrophotometric methods, the solubility of Ba (NO3 )2 inwater at 25.0 ° C was determined. Activity coefficients, f+ and f_ of Bat) and N0i(aq) ions in the saturatedsolution at 25.0 ° C were estimated upon the extended Debye —Hiickel theory and then, the constantK'sp =[Ba2+1f+ [NO-3 ]2 f 2 was evaluated. Comparing the value of thermodynamic solubi...
متن کاملA new structural technique for examining ion-neutral association in aqueous solution.
The method of intramolecular coordination number concentration invariance (ICNCI) is used on neutron diffraction with isotopic substitution (NDIS) measurements of aqueous solutions to separate the intra- and intermolecular contributions to the total intensities. Molecular dynamics simulations of corresponding systems are then used to interpret the ICNCI function. It is found that the ICNCI func...
متن کاملAnalysis of ion-association reaction in aqueous solution and its utilization by capillary zone electrophoresis.
Electrophoretic migration of analytes in capillary zone electrophoresis (CZE) reflects the dissolved status of analytes in solution, and the electrophoretic mobility is controlled to develop the resolution among analytes by adding a "modifier" to the migrating solution. Such addition of modifier is essentially the utilization of molecular interactions. Precise measurement of electrophoretic mob...
