烟草中氯的AAⅢ连续流动分析仪测定改进
Modification of AA Ⅲ Autoanalyzer Used for Determining Chloride in Tobacco
摘要
Abstract
In order to reduce the deviation in determining chloride in tobacco by A A DI autoanalyzer, the effects of dialyzer, wavelength for detection sample injection rate and color developing reagent concentration on the determination results were investigated, and the autoanalyzer was modified. The results showed that; 1) Tobacco extract could be purified by adding a dialyzer at reaction pipe. 2) Max adsorbance of reaction product was at the wavelength of 460 nm. 3) After modification, the recovery of the method were from 94.2% to 106.5% with RSD <5 %o The modified AA HI autoanalyzer is suitable for the accurate determination of chloride in tobacco.关键词
