Figure 3: Plots of log Pow values of 6 alkyl phenyl ketones versus their log k values using gemini (G1, G2) and SDS surfactant systems. MEKC separation conditions: 6.0 mM G1, 6 mM G2, 40.0 mM SDS in 10 mM phosphate buffer (pH 7.0); pressure injection, 50 mbar for 1 s; applied voltage, -30 kV for G1 and G2 and +30 kV for SDS; temperature, 25°C; UV detection at 254 nm. The regression equation for alkyl phenyl ketones in each pseudostationary phase is given in text.
