A highly sensitive polarographic method has been developed13; for the determination of trace amounts of germanium by combining two different chemical amplification methods in tandem. In this method germanium is treated with ammonium molybdate to form molybdogermanic acid (MGA) complex, the complex isolated by extraction with a mixture of diethyl ether and 1-pentanol and the molybdenum content of the complex determined by catalytic polarography. Conversion of germanium to MGA complex enhances the sensitivity since 1 atom of germanium reacts with 12 atoms of molybdenum to form the complex. The catalytic wave enhances the sensitivity by a factor of 40. By combining these two methods of amplification a dramatic improvement in overall sensitivit...
