A pencil graphite electrode (PGE) was modified by the electropolymerization of pyrrole-1-carboxylic acid (Py-CO2) to form a sensing film poly(pyrrole-1-carboxylic acid) (PPy-CO2) for sensitive determination Pb2+ and Cd2+ differential pulse anodic stripping voltammetry (DPASV). The porous structure PPy-CO2 uniformly distributes carboxylate group throughout coating selectively coordinate preconce...

Milk is very important component of human diet. The presence of over limit of heavy metal in milk may create significant health problems. In the present study, the direct determination of Zinc (Zn) heavy metal in milk samples of different brands was carried out by differential pulse anodic stripping Voltammetric technique at Hanging Mercury Drop Electrode (HMDE). Milk samples were processed by ...

      This study was conducted to determine the concentrations of metals (Zn, Cu, Pb, Cd and Hg) in two commercial fish species of the Persian Gulf (coast of Bushehr Province in Iran), as well as in the sea waters. The concentrations of metals were determined by using differential pulse anodic stripping voltammetry (DPASV). Two selected species were narrow-barred Spanish mackerel and tiger toot...

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...
