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 کاملAdsorptive stripping voltammetry - A new electroanalytical avenue for trace analysis
nickel can also be determined using a copper anode. Conditions are similar to those for nickel except that the applied potentials must be 200 mV more positive than for nickel. The anodic reaction rate constants with copper are typically somewhat greater than with nickel, however the applied potential results in increased background noise so that copper offers no signal-to-noise advantage over n...
متن کاملHeavy Metal Analysis by Anodic Stripping Voltammetry
Let’s say that you wanted to determine the heavy metal identities and concentrations in sediment and suspended solid samples obtained from present day Lake Nakuru. What technique would you use for this determination? You could use Atomic Absorption Spectroscopy (AAS) as was done in the article (Nelson 1998), but another technique, which is particularly good at detecting metals at the ppb level ...
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 کاملDetermination of Aminophylline by Cathodic Stripping Voltammetry
Aminophylline is determined by cathodic stripping voltammetry (CSV) in BR buffer, pH 7.5 at a hanging mercury drop electrode. The detection limit was 3x10 M after 60 s accumulation at -0.60 V versus Ag/AgCl reference electrode. The linear range demonstrated up to 5x10 M using CSV. The interference caused by some purine derivatives, anions and some metal cations on the peak current was studied. ...
