Abstract:
The potential toxicological properties of platinum group elements, usually present in real matrices at sub-ng/g level, explain the increasing interest in developing specific and sensitive analytical methods. In this work, a validation study was performed in order to ensure the fitness-for-purposes of procedures developed for quantifying platinum in tap water, beer and lettuce using an extremely sensitive method based on catalytic adsorptive stripping voltammetry. The work involved the estimation of selectivity, detection and quantitation limits, range, accuracy (trueness plus precision), uncertainty of measurement (UOM), robustness and recovery. The results are discussed in the light of the most recent literature findings
