Abstract
A method for determining Arsenic (As), Lead (Pb), Cadmium (Cr), Chromium (Cd), Nickle (Ni) in cigarette by graphite furnace atomic absorption spectrometry was developed and 10 cigarette brand samples were analyzed. The results showed that the optimized pyrolysis temperature and atomic temperature for As, Pb, Cr, Cd, Ni were 1 400, 700, 1 300, 600, 1 000 ℃ and 2 100, 1 750, 2 000, 1 300, 2150 ℃, respectively. The recoveries of As, Pb, Cr, Cd, Ni were 97.3％, 98.9％, 101.2％, 100.1％ and 102.6％with the RSDS of 4.6％, 3.0％, 3.6％, 2.2％ and 3.3％, and the detection limits were 0.147, 0.265, 0.146, 0.026 and 0.172 μg/L,respectively. Content of all the samples were Pb＞Cd＞Ni＞Cr＞As and As were between 0.101 ～ 0.234 μg/cig, Pb between 1.258 ～2.108 μg/cig, Cr between 0.129 ～ 0.680 μg/cig, Cd between 0.616 ～ 2.012 μg/cig and Ni between 0.380 ～ 0.801 μg/cig。关键词
