摘要

摘要:本文对以过酚酸盐络合物形式测定硝酸盐的方法进行了改进,目的是用Technicon自动分析仪自动测定烟草中硝酸盐的含量。改进后的方法可以自动测定从0.03%到烟草中通常出现的最大量的含水烟草提取物的硝酸盐含量。所描述的程序适用于每小时分析30个烟草样品。所得结果与其他手工方法的结果一致。应用这种分析方法获得的分析数据与使用3,4-二甲基苯酚(马斯特里赫特)的光度法得到的分析数据不同,平均少于0.01%的硝酸盐。该方法的变异系数为2.5%,对均质提取物和不同重量的烟草样品进行测量。

A Method for the Automatic Determination of the Nitrate Content of Tobacco / Eine Methode zur automatischen Nitratbestimmung im Tabak
Abstract The method for determining nitrate in the form of a perrhenate complex has been modified for the purpose of automatically determining nitrate contained in tobacco with the Technicon Autoanalyser. The modified method makes it possible to determine automatically nitrate contents of aqueous tobacco extracts ranging from 0.03 % to the maximum amounts usually occurring in tobacco. The procedure described is suitable for the analysis of thirty tobacco samples per hour. The results correspond with those furnished by other manual techniques. The analytical data obtained by application of this method of analysis differ from those resulting from the photometric method using 3,4-dimethylphenol (Maastricht) by, on an average, less than 0.01 % nitrate. The coefficient of variation of this method is, with measurements from a homogeneous extract as well as from various amount weights of one tobacco sample, 2.5 %.
