摘要 用电感耦合等离子体发射光谱法测定卷烟烟气中金属元素Na、K、Mg、Ca、Sr、Fe、Cu、Zn、Al的含量,以不同pH值的硝酸溶液做捕集剂,用自制的装置收集烟气.结果显示,在pH=0条件下,烟气中9种金属元素含量分别为9.381、0.536、0.262、4.963、0.01、0.115、0.041、0.085、0.154mg/5支,各种元素的检出限均低于0.018 9mg/L,元素回收率在90.5%-101.8%之间,相对标准偏差在2.18%-0.24%之间. The contents ICP-AES. The deferent pH of Na, K, Mg, Ca, Sr, Fe, Cu, Zn, A1 in cigarette smoke were determined by nitric solutions were used as traping agent,and self-made absorber was used to absorb cigarette smoke. The results showed that,the contents of nine elements was 9. 381,0. 536,0. 262, 4. 963,0.01, 0. 115,0. 041,0. 085,0. 154 rag/5 respectively under the condition of pH=0, detection lim- its of 9 elements were less than 0. 018 9 mg/L and values of recovery in the range of 90.5%-101.8%, RSDs in the range of 2.18%-0.24%.
