The Study of a New Method to Determine Copper Ion by Square-Wave Voltammetry-Extraction Iodometry at the Liquid/Liquid Interfaces
Figure 3
(a) Square-wave voltammograms of various
iodine concentrations in MIBK: amplitude 0.15 V and frequency 10 Hz, (b) the peak current versus concentration
of iodine in solution: the iodine concentrations (in mol/L): 0.0049, 0.0040,
0.0030, 0.0020, 0.0012, 0.00062, 0.00040, 0.00031.
