摘　　要：　研究了硅钼蓝分光光度法测定氟石中二氧化硅含量的快速分析方法。采用过氧化钠熔融试料,使用饱和硼酸消除氟的干扰。在选定的实验条件下,100ml显色溶液中,二氧化硅量在0～500μg符合比尔定律。方法快速准确,操作简便,用于氟石中二氧化硅的日常检测,可获得满意结果。A molybdenum blue photometric method for the determination of silicon dioxide content in fluorite was studied.The samples were melted by sodium peroxide.The interference from the fluorine were eliminated by some saturated boracic acid.In the selective conditions,in 100 ml colored liquid,when the content of silicon dioxide is 0～500 μg,it satisfys the bill law.The proposed method was fast,accurate,simple,and has been applied to determine silicon dioxide content in the fluorspar in the routine determination with satisfactory results.
