Heavy 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 کاملAptasensors Based on Stripping Voltammetry
Aptasensors based on stripping voltammetry exhibit several advantages, such as high sensitivity and multi-target detection from stripping voltammetric technology, and high selectivity from the specific binding of apamers with targets. This review comprehensively discusses the recent accomplishments in signal amplification strategies based on nanomaterials, such as metal nanoparticles, semicondu...
متن کاملAdsorptive Stripping Voltammetry in Lipophilic Vitamins Determination
The aim of this contribution was to check if adsorptive stripping differential pulse voltammetry (AdSDPV) is suitable tool for sensitive simultenous electrochemical detection of lipophilic vitamins. Retinol (vitamin A1), cholecalciferol (vitamin D3), α-tocopherol (vitamin E) and phylloquinone (vitamin K1) were selected as representatives. All electrochemical measurements were performed in two s...
متن کاملAnodic 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...
