Determination of microelements in tea-leaves and Chinese medicinal herbs by suspension sampling-flame atomic absorption spectrometry

Liu Lixing ,Du Weizhen,Wang Mingyong (Department of Applied Chemistry,Fushun Petroleum Institute,Fushun 113001),Huaxue Shiji,2000,22(1),36~38  
The suspension sampling technique was applied to flame atomic absorption spectrometry for successfully determining potassium,calcium,magnesium,manganese,copper,iron and zinc in tea leaves(jasmine tea and Xiang qing tea) and Chinese medicinal herbs (Angelica sinensis,Ligusticum wallichii and monkshood).The determination results of this method were consistent with those obtained by ashing method.The t test showed that no difference was found.The present method is convenient,rapid and accurate.
