容量法快速测定硼铁中硼

Determinating Boracium in Ferroboron Rapidly by Volumetric Analysis

氢氧化钠容量法测定硼铁中硼含量比其他方法的测定准确度高 ,因此采用氢氧化钠容量法较为实用。但由于容量法中溶样、浸取、分离、沉淀、洗涤、滴定等过程复杂 ,往往一步控制不严就会造成试验数据超过允许误差。通过大量反复试验 。

Determinating content of boracium by volumetric analysis of sodium hydrate was more accurate than other ways. However, because the processes such as dissolving ,infusion,partition, precipitation ,scouring ,titration etc.in volumetric analysis were complicated, the result would exceed the ranger of admitted error if one of them can't be controlled well. By a great deal of experiments, the several key points about measuring boracium more rapidly and exactly were mastered.
