Quartz crystal microbalance determination of trace metal ions in solution

Metal chelation and spatial profiling of components in crown ether functionalised conducting copolymer films

“…At the end of the surface assembly process, the quartz crystal microbalance (QCM) [30] was used to monitor the uptake by the film of metal ions from solution. This methodology has sufficient sensitivity to make such measurements at the monolayer level [31]. In the present instance, the process could be measured with high precision since the films were considerably thicker (i.e.…”

Regulating Copper‐Binding Affinity with Photoisomerizable Azobenzene Ligand by Construction of a Self‐Assembled Monolayer

“…In addition, the redox waves of Cu I/II were almost completely diminished in the 70th cycle (Figure 1). Decreases in the intensities of the redox peaks of the Cu ions have been observed in relatively weak binding of Cu ions to adsorbed molecules 8f. Therefore, the Cu‐binding affinity to the immobilized trans ‐L is relatively weak and the bound Cu ions may be easily desorbed from [Cu II ( trans ‐L)]/C 6 –Au.…”

Characterization, growth mechanism and application of network poly(bromophenol blue)

“…In addition, the effect of scan rate on the anodic peak current of Cu 2+ was studied by cyclic voltammograms. The oxidation peak current (i pa ) was directly proportional to the scan rate (v) over the range of 10-200 mV s À1 with the regression equation: i pa = 0.0270v + 1.074 (r = 0.9992), which suggested a adsorption-controlled process on the modified electrode surface [32,33].…”
