Abstract
A method for analyzing lead (Pb) and arsenic (As) in water-based adhesives for cigarette was developed by microwave digestion-graphite furnace atomic absorption spectrometry. The results of tested samples showed that: under the optimized conditions, in the linear ranges of 0-50 ug/L (Pb) and 0-20 ug/L (As), the linear coefficients, limits of detection, relative standard deviations (RSDs), and recoveries were 0.9992 and 0.9995, 0.075 and 0.037 mg/kg, 6.77% and 9.86% , 87.97%-92.35% and 93.37%-108.92% , respectively. The contents of Pb and As were less than 5 and 1 mg/kg, respectively. The method was suitable for the quantitative analysis of lead and arsenic in water-based adhesives for cigarette.关键词
