钼蓝光度法快速测定硅元素在硅铝钙钡合金中的应用

以氢氧化钠为熔剂，于聚四氟乙烯烧杯内进行低温快速熔融试样，并辅用H2O2助熔。样品熔融完全后，酸化、定容，用钼蓝分光光度法测定硅含量。本法具有操作简便、准确性好、快速、化验费用低、测定范围宽等特点。

Taking solidium hydroxide as flux, the sample is quickly melted at low temperature under assisted melting with H2O2 in the telflon beeker. After absolutely melted, the sample is acidized, quantified, and deter- mined of the Si content with molybdenum blue spectrophotometry. This approach has the characteristics of simple and convenient operation, accuracy, rapidity , low cost , wide range of determination and so on.
