Turner et al. [146] studied the automated electrochemical stripping of cadmium in seawater. 

Van den Berg and Huang [600] carried out direct electrochemical stripping of dissolved vanadium in seawater using cathodic stripping. Voltammetry was performed with a hanging mercury drop electrode. The detection limit was 0.3 nmol/1 after a collection period of 2 min.

The present chapter reviews recent research efforts aimed at developing new devices for in situ and on-site electrochemical stripping analysis of trace metals. It is not a comprehensive review, but rather focuses on new tools for decentralized metal testing, including remotely deployed submersible stripping probes, hand-held metal analyzers coupled with disposable microfabricated strips, and newly developed green bismuth film sensors.

The current research in the field of electrochemical indicators is mainly to find new labels that have powerful electrochemical signals. Metal NPs with well-defined redox properties that can be followed by electrochemical stripping techniques are of great interest [28,31].
