This paper used inductively coupled plasma mass spectrometry to determine the migration of aluminum,lead,cadmium,and arsenic elements in aluminum foil paper.By studying the migration experiments of different simulated liquids and exploring the treatment methods of simulated liquids,internal standard method and KED mode were used for testing under optimized conditions.This paper establishes an ICP-MS method for determining the migration amounts of aluminum,lead,cadmium,and arsenic in 5％citric acid and artificial tap water simulation solution.The linear relationship of the standard curve is greater than 0.999.The detection limit is 0.000 1-0.004 0 mg/kg,and the quantification limit is 0.000 33-0.020 00 mg/kg.The migration of various elements has different effects according to different migration conditions,and migration is more likely to occur under high temperature conditions;compared to artificial tap water,5％citric acid is more prone to element migration under the same migration conditions.Therefore,it is recommended to avoid using aluminum foil in high-temperature environments to reduce health risks caused by the migration of harmful elements.
