Application of Cold Vapor Differential Pulse Voltammetric Method for Determination of Mercury in Urine Samples

A Rapid Electrochemical Procedure for the Detection of Hg(0) Produced by Mercuric-Reductase: Application for Monitoring Hg-resistant Bacteria Activity.

“…For the latter applications, electrochemical techniques, especially their stripping versions, − are very suitable, as they allow sensitive, easy and rapid detection of traces of toxic metal ions even on line with simple and relatively inexpensive and portable apparatuses. , In particular, anodic stripping voltammetry (ASV) is a well established technique for quantifying trace of Hg 2+ in aquatic systems or biological samples. , Usually, in ASV performed from solutions, Hg(0) is accumulated on the electrode surface by reductive electrodeposition . A few cold vapor methods in combination with voltammetric determination of Hg(0) adsorbed on gold electrodes have also been utilized for determining Hg 2+ in aqueous matrices. − This approach has been used mainly to avoid interferences during the electrodeposition of Hg 2+ from dissolved organic matter and other ions. − …”
