Abstract:
A rapid determination method for emergency response to health crisis caused by metals in foods, was developed using microwave decomposition equipment and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The method was assessed for 18 elements (Al, As, B, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn, Tl and Zn) in 5 kinds of beverages and 7 kinds of foods. A single-laboratory method validation study was performed using food samples added with 20 mg/kg of each metal. Trueness was 88-108% and intralaboratory reproducibility was 0.2-11.3%. Time required for analysis was less than 3 hr. Thus, the presented method could be useful for rapid analysis of metals involved food poisoning cases.

01:18Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...

01:30EDTA: Direct, Back-, and Displacement Titration
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides...
