摘要
将动物胶凝聚重量法测定二氧化硅和钼蓝光度法测定二氧化硅的方法相结合,建立了磷灰石中二氧化硅含量测定动物胶凝聚重量法—滤液钼蓝分光光度法的新方法,该方法比原来的重量法、容量法具有更高的精密度和准确度。
This paper described a new method for determination of SiO2 in apatite, the new method is the combination of Gelatin coagulationgravimetric method and the molybdenum blue photometric method, it has been acquired more accurate and precise results by new method （Gelatin coagulationgravimetric method- molybdenum bluespectrophotemetry method）than volumetric method and gravimetric method.
