Simultaneous 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 کاملDisposable Copper-Based Electrochemical Sensor for Anodic Stripping Voltammetry
In this work, we report the first copper-based point-of-care sensor for electrochemical measurements demonstrated by zinc determination in blood serum. Heavy metals require careful monitoring, yet current methods are too complex for a point-of-care system. Electrochemistry offers a simple approach to metal detection on the microscale, but traditional carbon, gold (Au), or platinum (Pt) electrod...
متن کاملDetermination of Tl(I) Ions in Homeopathic Drugs by Differential Pulse Anodic Stripping Voltammetry
Objectives: The present study is focused on the determination of thallium (I) ions in homeopathic drugs. Methods: The determination was carried out using the Differential Pulse Anodic Stripping Voltammetry (DPASV) technique coupled with the flow-injection measuring system (FIA-DPASV). Results: The thallium content was analyzed in two commercial homeopathic preparations (Thallium aceticum 5CH an...

متن کاملDifferential pulse anodic stripping voltammetric determination of traces of copper with a tobramycin-Nafion modified electrode.
A Nafion-modified glassy carbon electrode incorporated with tobramycin for the voltammetric stripping determination of Cu2+ has been explored. The electrode was fabricated by tobramycin containing Nafion on the glassy carbon electrode surface. The modified electrode exhibited a significantly increased sensitivity and selectivity for Cu2+ compared with a bare glassy carbon electrode and the Nafi...
