“…5 The depolarization ratios of the di-, tri-, and tetra-coordinated silver cyanide complexes were also reported. 6 There have been numerous electrochemical methods using colorimetric titration, 2 impedance analysis, 7,8 capillary ion analysis, 9,10 and electrochemical quartz crystal microbalance measurement 11 to quantitatively determine the concentrations during the plating process. Electrospray mass spectrometry was employed to directly determine the ionic species in solutions.…”
