在醋酸-连苯三酚介质中,研究了阴极溶出法测定锗的适宜条件,于-0.25伏(对饱和甘汞电极)富集5分钟时,测定下限为1×10~(-9)M锗。拟定了高量锌中测定痕量锗的方法。
In the acetic acid-pyrogallol medium, the optimum conditions for the determination of germanium by cathodic stripping were studied. When the concentration of -0.25 V (for saturated calomel electrode) was 5 min, the lower limit of determination was 1 × 10 -9 M germanium. A method for the determination of trace germanium in zinc was developed.
