A procedure for the determination of cadmium, copper, manganese, and zinc in Turkish tobaccos, which were of different origins, years, and grades, and in the butt, ash, and smoke, which were obtained by smoking the cigarettes that were prepared manually from the said tobaccos in a smoking apparatus, was devised as proposed. The collected samples were digested by wet ashing technique by using HNO3-HClO4 and were analyzed by flame atomic absorption spectrometry with satisfactory recoveries (94% to 98%). The regression coefficients were above 0.99, and the detection limits were in the range of 0.03-0.12 mg/L(-1). The performance and accuracy of the method was tested by analyzing "Certified Reference Material GBW 08501-Peach Leaves." The determined values were in agreement with the standard values for the heavy metals analyzed. Thus, it was concluded that the developed method could offer a wide range of application for establishing a relationship between the makeup and composition of tobacco plant, products, ash, smoke, and smoking.
设计了一种用于测定不同产地、年份和等级的土耳其烟草以及由这些烟草手工卷制的香烟在吸烟装置中吸烟后得到的烟蒂、烟灰和烟气中镉、铜、锰和锌的方法。收集的样品通过使用 HNO3-HClO4 的湿法灰化技术进行消解，并通过火焰原子吸收光谱法进行分析，回收率令人满意（94%至 98%）。回归系数均大于 0.99，检测限在 0.03-0.12mg/L(-1)范围内。通过分析“GBW 08501-桃叶认证参考物质”测试了该方法的性能和准确性。分析的重金属的测定值与标准值相符。因此，可以得出结论，所开发的方法可以为建立烟草植物、产品、烟灰、烟气和吸烟之间的成分和组成关系提供广泛的应用。
