Abstract

The work aims toestablish inductively coupled plasma mass spectrometry technology to simultaneously detect 9 heavy metal elements including arsenic, cadmium, cobalt, chromium, copper, nickel, lead, selenium, and antimony, and determine the content and migration of heavy metals in different wood tableware. HNO3-H2O2 was selected as the digestion solution and microwave digestion was adopted for content determination. 4 different simulated substances, namely 4% acetic acid, 10% ethanol, 50% ethanol, and 95% ethanol were selected, and the migration of the samples was determined by the pre-treatment method of immersion migration. 72Ge, 209Bi, 115In, and 45Sc were selected as internal standard elements to monitor and correct signal differences and a four-stage rod collision reaction cell technology was employed to eliminate mass spectrometry interference and optimize instrument operating conditions. The linear correlation coefficient r2 of migration determination was not less than 0.999 9, the detection limit range was 0.002-0.2 μg/L and the recovery range of standard addition was 92.3%-103.1%. The linear correlation coefficient r2 of migration determination was not less than 0.999 1, the detection limit range was 0.002-3.0 μg/L, and the recovery range of standard addition was 91.7%-107.4%. This method is characterized by its speed, simplicity, and high accuracy, and is suitable for determining the content and migration of wood tableware.
