Abstract:Objective To establish a method of simultaneously determine the element content of aluminum (Al), chromium (Cr), manganese (Mn), cobalt (Co), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), tin (Sn), antimony (Sb), barium (Ba), mercury (Hg), lead (Pb) in polypropylene (PP), polyethylene (PE), polyester (PET) pharmaceutical packaging. Methods After microwave digestion of samples, with scandium (Sc), germanium (Ge), indium (In) and bismuth (Bi) as internal standard, the content of the above elements were determined by inductively coupled plasma mass spectrometry (ICP-MS) method at the same time, the ICP-MS power was 1550 W, sampling depth was 7.6 mm, plasma gas, carrier gas and auxiliary gas flow were 15.0, 0.86, 1.0 L/min respectively, the pump speed was 0.10 r/s, the atomizing chamber temperature was 2℃, reaction mode was helium, data was collected for three times. Results The linear relationship between the determined elements was good, r = 0.9986-0.9999, the sample recovery rate of each element in PP, PE and PET is between 85.8% and 99.1%, and the RSD was 1.5%-4.7% (n = 9). Conclusion The method is fast, simple, sensitive, and accurate. It can be used for the determination of various metal elements in plastic medicine packaging made of different materials.
