Numerical simulations based on the time dependent backward implicit method are used to develop the theory of anodic stripping voltammetry carried out under hydrodynamic conditions using mercury thin film wall-jet electrodes. The peak shape is shown to be highly sensitive both to electrolyte flow rate and to the potential sweep rate. The simulations permit visualization of concentrations both in...

Recently, the scientific community has shown a great interest about Organ-on-Chip (OoC) devices, special kind of micro-fabricated platforms capable recapitulating human physiology implementing traditional cell culture methods and concept in vivo studies. Copper ions represent cellular micronutrient that must be monitored for its potential hazardous effects. The application electrochemical analy...

ronment, the determination of trace Hg(II) is important. Atomic absorpt ion and inductively coupled plasma spectroscopic methods are currently widely used. Many publications on this subject focus on electrochemical methods (anodic and potentiometric stripping voltammetry) at a variety of electrode materials. Glassy carbon, goldplated glassy carbon, screen-printed carbon, platinum (Pt) and gold ...

-The distribution of toxic heavy metals was studied throughout the process of treatment of domestic wastewater by stabilization ponds. The concentrations and distribution of free and bound zinc, cadmium, lead and copper through the various stages of a treatment plant were analyzed by Anodic Stripping Voltammetry (ASV). Only a slight decrease in the total metals concentration was observed during...

Electrochemical methods of analysis are of practical advantage in many areas. These include use for determining relevant values in trace-metal pollution studies and remediation; understanding the roles these metals play in biological systems and medicine; characterising materials in the microelectronics industry; developing new energy technologies; and even in fields such as archaeology and for...
