(a) Effect of detection medium pH on the peak current of 4 × 10−6 mol/L MBC. (b) Effect of pH of accumulation medium on the electrode response. For both curves, preconcentration was performed for 10 min in 0.01 mol/L acetate buffer (pH 5) containing 4 × 10−6 mol/L MBC, while detection was performed in 0.1 mol/L ammoniacal buffer (pH 9). Other experimental conditions as in Figure 2.
