前言在钢铁及有色金属的日常分析工作中,突出的感到铝的测定是一个比较复杂而困难的问题,例如:在钢铁中测铝,消除铁对铝的干扰问题;在钢合金中:钢、铁及其他杂质与铝的分离问题等等。根据化学通报第七期(48-总432)无锡青钢的快速测定一文,利用电位滴定法测定了无锡青铜中之铝,我们利用这种方法解决了铸铁(包括部分合金钢)及铝合金中铝的测定问题。现将我们所作的实验及在实验过程中所积的点滴经济分述如下,供大家参考。
Foreword In the daily analysis work of steel and non-ferrous metals, the prominent feeling of aluminum is a complicated and difficult problem, such as measuring aluminum in steel to eliminate the interference of iron to aluminum; in steel alloys: steel, Iron and other impurities and the separation of aluminum and so on. According to the rapid determination of Wuxi Qinggang from the seventh issue of Chemical Bulletin (48-total 432), the aluminum in Wuxi bronze was measured by potentiometric titration, and we used this method to solve the problem that the cast iron (including some alloy steel) and the aluminum alloy Determination of aluminum problems. Now we have made the experiment and in the experiment the cumulative economic points are as follows, for your reference.
