Abstract
Recent advances in voltammetry are discussed. The main advances made are related to the deposition step which now normally utilizes deposition by adsorption rather than by plating. This change suggests that equipment could now be usefully redesigned to provide fast wave-forms such as the high-frequency square-wave modulation as standard. An additional advantage of adsorptive deposition over voltammetry is that the opportunity is provided to utilize catalytic effects to enhance the sensitivity further. Voltammetry is especially suited for the automated monitoring of the concentration and chemical speciation of trace elements in natural waters. It is in this area that is has an advantage over multiple-element analytical techniques.
