Application of the combined electrochemical quartz crystal microbalance and probe beam deflection technique in deep eutectic solvents

- The EQCM/PBD method has for the first time been applied to metal deposition/dissolution processes in deep eutectic solvents
- The PBD responds to solution phase chemistry, while the E and QCM probes respond to interfacial processes only
- The combination of electrochemical (E), gravimetric (QCM) and optical (PBD) responses provides diagnostic capability
- EQCM/PBD data reveal the influence of Ag/Cl− complex speciation in the high chloride concentration ionic liquid
- The PBD response reveals the intrusion of solubility limitations into Sn anodic stripping
