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 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...
متن کاملAnalysis of Chemical Equilibria in Aqueous Solution Related with Separation Development Using Capillary Zone Electrophoresis
Capillary zone electrophoresis (CZE) has become a popular technique for the analysis of ionic substances. The separation mechanism is based on the differences in electrophoretic mobility of analyte ions, as well as on the electroosmotic flow. Although the separation efficiency in CZE is amazingly high, various types of interacting reagents are often used to control the electrophoretic mobility ...
متن کاملSample-stacking techniques in non-aqueous capillary electrophoresis.
In sample-stacking techniques, the detection limit cannot be improved by simply increasing the length of the sample solution, because the individual electrophoretic parameters must be optimized. In an attempt to increase the amount of sample injected, as well as to focus them onto a small zone, two novel methods are proposed. One of these employs an "ultra-high conductivity zone", which was ins...
متن کاملThermodynamic study of ion- association in KNO3 solution in the mixed solvent (water +methanol)
The solubility of KNO3 in the mixed solvent (water 85%+methanol 15%) were determined by using solvent evaporating method at different temperatures (25, 30, 40, 50, 60 ;C). In addition the equilibrium constant of ion pair formation, KIP, for K+NO3 – ion-pair on the basis of Fuoss contact ion pair model was calculated. Upon choosing the extended Debye-Hückel model for estimating the mean activity...
