分光光度法测定冲洗液中微量杂质

Determination of micro impurity in purge liquid by spectrophotometry

详细描述了用分光光度计测定冲洗液中 Si、 、 的分析方法,利用该方法对冲洗液 Al Fe进行测定,证明该检测方法简便、快速、准确,能够满足生产需要。通过大量的实验数据总结出规律,确定了无烟煤的处理周期,为以后的工作积累了经验。

The spectrophotometry process for the impurities determination including Si, Al, Fe, et al. was described in detail. For its simplicity, fast and accuracy, when determine the purge liquid by this process, it would be found that the process can meet the need of industrial processing. Some regulations about this process has been summarized form a large number of experimental data. And the period of anthracite treatment has been set. All this would be useful experiences for work in future.
