Abstract: Affinity capillary electrophoresis was applied to investigation of solvent effects on stability constant of dibenzo-18-crown-6 complex with potassium ion in mixed hydro-organic solvents at different water/methanol, water/ethanol and water/propan-2-ol ratios. The apparent stability constants of the complex were found to be strongly decreasing with increasing molar fraction of water in the mixed solvents.
Keywords: affinity capillary electrophoresis; binding constant; solvent effect
