本文提出应用锗-连苯三酚络合物的吸附催化波测定高阻镍合金中锗的方法。对各种影响因素进行了研究,确定了底液的组成。对干扰元素的试验证明本法干扰少。锗浓度在0.02～0.2毫克/50毫升范围内与催化电流成线性关系。同时对锗-连苯三酚络合物极谱波的性质作了初步探讨。与用邻苯二酚测定锗的方法相比较,本法具有灵敏度较高、稳定性较好且成本低的特点。经过一年多来的实际试样分析证明:这是一个无须分离、简便、快速和准确的方法。
In this paper, we propose a method for the determination of germanium in high resistance nickel alloys by adsorption catalytic wave of germanium-pyrogallol complex. Various influencing factors were studied to determine the composition of the bottom liquid. Experiments on interfering elements prove that this method has less interference. Germanium concentration in the range of 0.02 ~ 0.2 mg / 50 ml linear with the catalytic current. At the same time, the properties of polarographic wave of germanium-pyrogallol complex were discussed. Compared with the method for the determination of germanium with catechol, the method has the characteristics of high sensitivity, good stability and low cost. After more than a year of actual sample analysis proved: This is a non-separation, simple, fast and accurate method.
