Cloud Point Extraction for Electroanalysis: Anodic Stripping Voltammetry of Cadmium.
Cloud point extraction (CPE) is a well-established technique for the preconcentration of hydrophobic species from water without the use of organic solvents. Subsequent analysis is then typically performed via atomic absorption spectroscopy (AAS), UV-vis spectroscopy, or high performance liquid chromatography (HPLC). However, the suitability of CPE for electroanalytical methods such as stripping...
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 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 کاملAnodic stripping voltammetry of lead and cadmium using a mercury ®lm electrode and thiocyanate
It is well known that lead and cadmium can be determined with good sensitivity using anodic stripping voltammetry (ASV) and a mercury ®lm electrode. However, the mercury ®lm formation is poorly reproducible and cannot fully be removed electrochemically. We have evaluated procedures to improve the reproducibility and sensitivity of the ASV method and found that in the presence of thiocyanate the...
