Figure 5From: Electrochemical determination of hydroquinone using hydrophobic ionic liquid-type carbon paste electrodesNyquist plots of (a) M-CPE, (b) MIL-CPE, and (c) IL-CPE in a PBS (pH= 7.0) containing 10 mmol L-1H 2 Q. The applied perturbation amplitude was 5 mV (vs.OCP), and the frequencies swept from 104 Hz to 10-1 Hz.Back to article page
