Lab-on-a-Chip Sensor with Evaporated Bismuth Film Electrode for Anodic Stripping Voltammetry of Zinc.
In this work, we report on the development of a lab-on-a-chip electrochemical sensor that uses an evaporated bismuth electrode to detect zinc using square wave anodic stripping voltammetry. The microscale electrochemical cell consists of a bismuth working electrode, an integrated silver/silver chloride reference electrode, and a gold auxiliary electrode. The sensor demonstrated linear response ...
متن کاملSimultaneous determination of lead, cadmium, copper and zinc in Infant formula by anodic stripping voltammetry
Determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. Long-term exposure to low levels of toxic metals could be important, especially in relation to children. Differential Pulse Anodic Stripping Voltammetry (DPASV) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...

متن کاملRapid micromethod for blood lead analysis by anodic stripping voltammetry.
We describe a rapid microscale procedure for blood lead determination by anodic stripping voltammetry. Results correlate well with those obtained by atomic absorption spectroscopy. The procedure involves use of a metal-exchange reagent, which rapidly releases bound lead from its macromolecular binding sites, thus eliminating a long and cumbersome perchloric acid digestion procedure. Reproducibi...
متن کاملOn-line Preconcentration and Determination of Trace Heavy Metals by Sequential Injection-Anodic Stripping Voltammetry Using Bismuth Film Screen-printed Carbon Electrode
An automated on-line preconcentration method was developed for simultaneous determination of Pb(II), Cd(II) and Zn(II) by square-wave anodic stripping voltammetry (SWASV) using bismuth film screen-printed carbon electrode (Bi-SPCE). The preconcentration of metal ions was performed with a mini-column of a chelating resin, which was installed on a switching valve in the automated system consisted...
