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 کاملSimultaneous Determination of Zinc, Cadmium, Lead and Copper in Water by Potentiometric Stripping Analysis
Analysis of zinc (In) cadmium (Cd), lead (Pb) and copper (Cu) in drinking and irrigation waters by potentiometric stripping analysis (PSA) is described. The pH and EC of waters were also determined. The results for zinc and copper were compared with those obtained by atomic absorption spectrophotometry (AAS) which indicated a significantly (P<0.01) strong correlation (r = 0.994 and 0.984 for In...

متن کاملSimultaneous Determination of Trace Amounts of Lead and Zinc by Adsorptive Cathodic Stripping Voltammetry
A selective and sensitive method for simultaneous determination of lead and zinc by adsorptive differential pulse cathodic stripping voltammetry is presented. The method is based on adsorptive accumulation of the complexes of Pb (II) and Zn(II) ions with Dopamine onto hanging mercury drop electrode (HMDE), followed by reduction of adsorbed species by differential pulse cathodic stripping voltam...
