Electrochemical Behavior of Ni(II)-Salen at the Mercury Electrode
Figure 4
The effect of accumulation time on the current of the square-wave stripping peak for 2.1 × 10−7 mol L−1 Ni(II)-salen complex in phosphate buffer (0.02 mol L−1, pH 7.0). Accumulation time at −700 mV with stirring. Potential step height (-step): 4 mV. SW-: 30 mV and SW-: 30 Hz.
