ICP–AES method was developed for the simultaneous determination of Zn, Pb, Cd, As, which released from food packaging aluminum foil. The sample was extracted with 4%acetic acid, placed at the room temperature for 24 h. The analytical spectral lines were Zn 213.856,Pb 220.353,Cd 226.502,As 193.759 nm. The results showed that the linear rang of 4 elements were 0.3–5.0, 0.1–2.0, 0.01–0.2, 0.03–0.5 mg/L, and the linear equations were Y=23 487.27X+769.79, Y=6 713.35X+38.46, Y=30 562.52X+362.02, Y=6 448.97X+13.57 with correlation coefficients of 0.999 5, 0.999 8, 0.999 9, 0.999 9, and the detection limits were 0.009 6, 0.003 7, 0.000 4, 0.013 9 mg/L for Zn, Pb, Cd, As, respectively. The spiked recoveries ranged from 96.5%to 100.5%with relative standard deviations of 1.38%–3.06%(n=6). The results demonstrated that the method was simple, rapid and accurate.
