Vollrath, T. Otz, C. Hohl, H. Seiler] Summary: A microwave digestion procedure and an oxygen flask combustion procedure were developed for the determination of cadmium and lead in plastic materials. A comparison with conventional wet ashing shows acceptable agreement. Different types of plastics such as polyvinylchloride, polypropylene, polyethylene, polystyrene, polyamide, and polyethyleneterephthalate were investigated. The precision of microwave digestion was determined within a series and from day to day. The results obtained by flame atomic absorption spectrometry were verified by measurement with inverse voltammetry. Overall, microwave digestion as well as oxygen flask combustion are time saving and cost-effective dissolution procedures to supervise the legal cadmium limit in plastics.
