为建立检测卷烟滤棒中铅含量的微波消解-石墨炉原子吸收光谱方法，对样品前处理条件和分析测试条件进行了优化，最终确定最优的条件：灰化温度、原子化温度、基体改进剂分别为1000℃，2000℃和1.0 g/L硝酸钯。在优选的实验条件下，方法的检出限为0.084μg/L，相对标准偏差小于3.26%，加标回收率范围在86.3%~99.8%之间。该方法简便、准确、灵敏度高、重复性好、回收率高，适合于卷烟滤棒中铅的测定。

A method to determine lead content in cigarette filter using microwave digestion and graphite furnace atomic absorption spectrometry was developed. Experimental conditions were optimized. Ashing temperature, atomization temperature and matrix modifier applied were 1000℃, 2000℃and 1.0 g/L of palladium(II) nitrate dihydrate. Under optimum conditions, the detection limit was 0.084μg/L, while relative standard deviations were less than 3.26%. The recoveries of samples ranged from 86.3%to 99.8%. Result show that the method is simple, accurate, sensitive, reproducible, and validate for the determination of lead in cigarette filters.
