Description | Heavy metals (cadmium, lead, zinc) determination in biological matrixes belongs to actual problems concerning food hygiene, foodstuffs quality and food chemistry. Cadmium, lead and chromium belong to heavy metals group characterised by high toxicity. Other important group of heavy metals is represented by essential components such as zinc, cuprum and cobalt, which are necessary for regular function of enzymes. In our work we used electroanalytical techniques for heavy metals determination in biological matrix (apple). In our recent works we found out that the electroanalytical techniques are effective tool to detect very low heavy metals concentrations even in the biological matrix. In addition, it is able to determine concentration of free heavy metal and after eventual sample mineralization also its fixed form by the mentioned techniques. It is very suitable to determine heavy metal concentration in single run (simultaneous determination) for routine analysis. We simultaneous determined cadmium, lead and cuprum by differential pulse anodic stripping voltametry voltammetry (DPAV) in the presence of acetate buffer (pH 4.6). |
