遵照伟大领袖毛主席关于“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的教导,我们为了寻找可以连续测定锌精矿中铜、铅、镉的极谱底液,作过一些试验。试验结果表明:用10%盐酸—10%乙酸铵为底液,并利用示波极谱仪有较高的分辨能力和抗先还原离子的干扰等特点,可以连续测定锌精矿中铜、铅和镉三个元素。测定含量范围为0.01%～5%。现将试验情况及分析方法叙述如下。
Following the teachings of Chairman Mao, the great leader, on the principle of “human beings always summarize experiences, discoveries, inventions, innovations, and advances,” we sought to find a way to continuously measure the concentrations of copper, lead and cadmium in zinc concentrates Spectral fluid, made some experiments. The experimental results show that the determination of copper and lead in zinc concentrate can be continuously determined by using 10% hydrochloric acid -10% ammonium acetate as the bottom liquid and utilizing the high resolving power of oscillopolarographic polarography and the interference of anti-reduction ions. And cadmium three elements. Determination of the content range of 0.01% to 5%. The test situation and analysis methods are described below.
