本工作选择了锗-苏木精-钒(Ⅳ)催化极谱测定锗的最佳条件,研究了催化波的性质,观察了共存离子的影响,拟定了测定矿石中痕量锗的流程。方法的检测限为n·10~(-5)ppm Ge,浓度为2×10~(-4)～8×10~(-2)ppm Ge时,与波高成线性关系。当直接测定矿石中0.073%Ge时,标准偏差为0.0014,变动系数为1.9%。 In this work, the optimum conditions for germanium determination by germanium-hematoxylin-vanadium (Ⅳ) were determined. The catalytic wave properties were investigated. The effect of coexisting ions was observed. The determination of trace germanium in ore was also proposed. The detection limit of this method is n · 10 -5 ppm Ge, with a linear relationship with wave height at a concentration of 2 × 10 -4 to 8 × 10 -2 ppm Ge. When the direct determination of ore 0.073% Ge, the standard deviation of 0.0014, coefficient of variation of 1.9%.
