Dissolution kinetics, scanning electrochemical

The kinetics of AgGl dissolution in aqueous solutions without supporting electrolyte have been studied utilizing well-defined and high mass transport properties of the scanning electrochemical microscope [376]. An ultramicroelectrode probe positioned close to the AgGl surface was used to induce and monitor dissolution of the salt via reduction of Ag+ from the initially saturated solution.

Workers have also used a number of commercially available FEM packages to allow the simulation of immiscible liquid-liquid interfacial measurements [125-127] and approach curves for scanning electrochemical microscope applications [128]. Compton and coworkers have also used a commercial FEM package to model coupled heat and mass transport at a wire [129], and dissolution kinetics in flow-through devices [130].
