参比溶液

如果溶液的颜色不比水或溶剂或参比溶液B9深，那么溶液是无色的。

A solution is colourless if it has the appearance of water R or the solvent or is not more intensely coloured than reference solution B9 .

由于SiC中的总硅量高达70%左右，所以用500μg／100ml的标准SiO2溶液作为参比溶液，以硅钼蓝示差分光光度法测定SiC超细粉末中的总硅量。

Because the total silicon content in SiC amounts is about to 70 % , We have taken a standard solution containing SiO2500 μ / 100ml as a reference solution to determine the total Si content in SiC by differential spectrophotometry of silicon - molybdenum blue .
