Abstract:

A method for the determination of nine heavy metals including lead, nickel, cadmium, chromium, copper, arsenic,
manganese, zinc, and titanium in aluminum-plastic composite packaging by inductively coupled plasma mass spectrometry
(ICP-MS) has been developed. The limits of detection (LODs) were between 0.01 and 1.62 μg/kg and the limits of
quantitation (LOQs) were between 0.03 and 5.35 μg/kg. Good linearity with correlation coefficients ≥ 0.99 was obtained.
The recoveries ranged from 82.6% to 119.3% with relative standard deviations (RSDs) of 0.1%–12.3% at three spiked
concentration levels (20, 50, and 100 μg/kg). The method is rapid, simple, and has good accuracy and precision. It is suitable
for the determination of heavy metals in aluminum-plastic composite packaging.
