Determination of Germanium in Vegetable by Microwave Plasma Torch Atomic Emission Spectroscopy(MPT-AES)

DONG Hong-xia, ZHAO Xiao-song, SUN An-na, LI Ming-tang (College of Resources and Environmental Science,Jilin Agricultural University,Changchun 130118,(China))  
A new method, microwave plasma torch atomic emission spectroscopy(MPT-AES),was used to determine trace elements germanium in vegetable and soil. The samples were wet ashed and then dissolved by hydrochloric acid. Some experimental parameters are discussed and optimized. Microwave power is 80 W, negative high pressure is 800 V, wavelength is 265.118 nm, support gas is 0.50 L/min, carrier gas is 0.90 L/min.The recoveries are in the range of 92.77%~95.60% and the RSD is less than 4.00%.The merits of the method are high sensitivity,rapidity,less sample quantity and so on.
