【Abstract】 The determination of trace germanium in human hair by polarographic adsorptive complex catalytic wave of Ge （ Ⅳ ）-catechol-sodium bromate has been presented. The peak potential of polarographic wave is at-0. 85V（μs. SCE）, the detection limit of Ge（ Ⅳ ） is 1.0 × 10^-9 mol/L ,and the linear range is 1. 0× 10^-9-7.0×10^-6 mol/L for Ge（ Ⅳ ）. The recovery of the addition experiment of the sample is 90. 3%-92.1%.更多还原
