硅酸盐中二氧化硅是否分离对返滴定法检测三氧化二铝结果的影响

Whether Silica Separates from Silicate Would Lead to a Different Result on Quantitative Detection of Aluminum Oxide through Back Titration

文章讨论了硅酸盐中的二氧化硅分离与否,对氟化钾返滴定法检测三氧化二铝的结果是否存在影响。结果表明,硅酸盐中的二氧化硅分离之后,三氧化二铝的分析结果更为准确、可靠;不分离二氧化硅直接检测硅酸盐中的三氧化二铝是不可取的分析手续。

The article discusses whether the silica separates from silicate or not causes the different result on quantitative detection of aluminum oxide through potassium fluoride back titration. The results showed that, after the separation of silica, aluminum oxide analysis is more accurate and reliable; no separation of silica directly detected silicate aluminum oxide is undesirable analysis procedures.
