一、前言:在生产大跃进中,钨矿化验工作者,都在探讨钨的快速分析。到目前为止,虽已从过去三天报出结果的辛可宁方法,进而改为一天报出结果的硝酸铵法,尽管在时间上缩短了二倍,但仍不能满足生产上的需要。分析钨还没有一个较好的容量方法。在全苏标准法中曾经提到过采用酸碱滴定法来代替钨的重量分析,目前亦未在我国被广泛采用。在建设社会主义的总路线光辉照耀下,经过一连串的实验,我认为下述方法还能令人满意,现在把这个方法简单介绍于后。
I. Preface: In the Great Leap Forward of Production, tungsten mine laboratory workers are all discussing the rapid analysis of tungsten. So far, the cinchonine method, which has reported its results in the past three days, has been replaced by a day’s report of the ammonium nitrate method, which, although twice as short in time, still fails to meet its production needs. Analysis of tungsten does not have a better capacity method. In the whole Soviet Union standard method has mentioned the use of acid-base titration instead of gravimetric analysis of tungsten has not been widely used in our country. Under the brilliance of the general line of building socialism, after a series of experiments, I think the following method is still satisfactory. We will now introduce this method briefly.
