本文提出以乙醇作稳定剂,pH为1.2时使硅钼黄显色,然后用混合还原剂还原为硅钼蓝,示差分光光度法测定其吸光度,以计算机作图,算出水泥熟料中SiO_2含量。
In this paper, ethanol was used as a stabilizer to make silicon molybdenum yellow at pH 1.2, and then reduced to silicon molybdenum blue with a mixed reductant. Absorbance was measured by differential spectrophotometry. Calculated by computer, the content of SiO_2 in cement clinker .
