Simultaneous Determination of Ba,Co,Cu,Fe,Li,Mn,Zn and Sb Migration Quantities in Polymer Laminated Steel Cans by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES)

Inductively coupled plasma-atomic emission spectroscopy(ICP-AES)was used for the simultaneous determination of Ba,Co,Cu,Fe,Li,Mn,Zn and Sb migrations in polymer laminated steel cans.The food simulation solution,migration conditions and the analytical wavelengths for the elements determined were systematically evaluated,and the plasma parameters optimized.The detection limits of Ba,Cu,Li,Mn,Fe,Co,Zn and Sb were 0.0006,0.0016,0.0012,0.0006,0.0008,0.0004,0.0045 and 0.0150mg/kg,respectively.The RSD was between 0.87% ~ 2.28%(n = 8),and the recoveries ranged from 98.9% to 104.7%.The method was suitable for the rapid determination of Ba,Co,Cu,Fe,Li,Mn,Zn and Sb migrations in polymer laminated steel cans.
