Study on Determination of Potassium in Tobaccoby Continuous Flow Analysis HUANG Hai-TaLoi ZhongLIU Wei WANG LanYANG Guang-Yu (Analytical Laboratory of Yunnan Academy of Tobacco Science，Kunming 650106，P. R. China ) Abstract The determination of potassium in tobacco was studied by ALLIANCE .The suitable condi-tion for the extracting potassium was selected， and compared with sodium tetraphenyl borongravimetric method. Based on this，a new method for the continuous determination of potassiumwas established. This method gives a guarantee for the rapid and accurate determination of potas-sium in tobacco. Key words Continuous Flow Analysis，Tobacco， Potassium.
