Manipulation and measurement of pH sensitive metal–ligand binding using electrochemical proton generation and metal detection

Abstract

Generator-detector electrodes can be used to both perturb and monitor pH dependant metal–ligand binding equilibria, in situ. In particular, protons generated at the generator locally influence the speciation of metal (Cu²⁺) in the presence of ligand (triethylenetetraamine), with the detector employed to monitor, in real time, free metal (Cu²⁺) concentrations.
