Method for detecting content of silicon dioxide

According to the method for detecting the content of the silicon dioxide, wherein the silicon dioxide in a sample is converted into silicate, and the content of the silicon dioxide is indirectly measured by measuring the content of the silicate. Compared with an existing detection method, the method is high in precision, good in accuracy, simple and convenient to operate, high in universality and suitable for quantitative detection of silicon dioxide in drugs, food and other samples. 本发明提供了一种二氧化硅的含量检测方法，将样品中的二氧化硅转化为硅酸盐，通过测定硅酸盐的含量间接测定二氧化硅的含量。与现有检测方法相比，本发明方法精密度高、准确性好，且操作简便、通用性强，适用于药品、食品及其它样品中二氧化硅的定量检测。
