Anodic stripping voltammetry of trace metals by batch injection analysis
The application of batch injection analysis to the determination of trace metals in samples of volume s 100 ~1 by square wave anodic stripping voltammetry has been investigated in detail, using a programmable electronic micropipette. The in situ formation of a mercury film on a glassy carbon electrode substrate, the influence of preconcentration time, injection rate and injected volume of analy...
متن کاملDetermination of ultra trace of thiosemicarbazide by adsorptive stripping voltammetric method
In the present work, an adsorptive stripping voltammetric method using a hanging mercurydrop electrode (HMDE) was described in order to determine the ultra trace of thiosemicarbazidein different real samples. The method is based on accumulation of thiosemicarbazide on mercuryelectrode. The potential was scanned to the negative direction and the differential pulse strippingvoltammograms were rec...
متن کاملAutomatic system for the determination of metals by anodic stripping potentiometry in non-deaerated samples
An automatic system for the determination of Zn, Cd, Pb and Cu by anodic stripping potentiometry using the oxygen dissolved in the sample as oxidant is reported. The system relies on the use of a PC-compatible computer for instrumental control and data acquisition and processing.
متن کاملDetermination of Trace Mercury (Hg(II)) by Anodic Stripping Voltammetry at a Gold Electrode
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 ...
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...
