| Abstract: | The composite laminated food packing bag was soaked in 4% acetic acid. The content of Pb, Cd, Cr, Ni, Cu, As in sample solution was determined by GFAAS. The absorbance and mass concentration had good linear relation. The liner calibration curves regression coefficients were 0.998 9-0.999 9, and the method detection limit were 1.04, 0.05, 0.98, 1.00, 0.97, 0.96 μg/L for Pb, Cd, Cr, Ni, Cu, As. The relative standard deviations of detrtmination results were 1.03%-6.81%（n=6）, and the recoveries were 95.11%-104.52%. |
