Determination of Germanium in Mongolia Medicine Naru Sanwei Pill by Polarography

ZHAO Danqing,SUN Zhancai,ZHANG Li (College of Chemistry and Chemical Engineering,Inner Mongolia University for Nationalities, Inner Mongolia Tongliao 028042,China)  
The amount of Ge(Ⅳ) in pH 1.30 H2SO4 including 3,4-dihydroxy benzaldehyde supporting electrolyte was determined by differential pulse polarography.The peak potential is located at Ep=-0.54 V with peak current proportional to concentration of Ge(Ⅳ) in 1.04×10-5~1.05×10-4mol·L-1.This method was applied to the determination of total germanium,organic germanium and inorganic germanium in Mongolia medicine Naru Sanwei pill with satisfactory results.
