本文论述JP-303极谱法快速测定铜精矿中的铅量。用国家标准原子吸收法进行了对照,结果令人满意。共存元素对铅的测定无明显影响,回收率在97.5%~103.8%之间,适用于铜精矿中0.01%以上铅的测定。
This paper discusses the rapid determination of lead in copper concentrate by JP-303 polarographic method. With the national standard atomic absorption method for control, the results are satisfactory. The coexisting elements have no obvious effect on the determination of lead, the recovery rates are between 97.5% and 103.8%, which is suitable for the determination of lead above 0.01% in copper concentrates.
