摘要
目前利用氟硅酸钾容量法测定锰矿中二氧化硅含量还没有报道。采用硅氟酸钾容量法,通过称样量、融样方式、酸化体积等条件进行优化实验,实现了容量法快速测定锰矿中二氧化硅的含量。实验数据的相对标准偏差小于1%。测量值与认定值一致,测量结果满足GB/T 1509-2006《锰矿石硅含量的测定高氯酸脱水重量法》允许差的要求。
At present, fluoride potassium silicate Volumetric method analysis silica content in manganese ore has not reported, through experiments optimized the parameters of fluoride potassium silicate Volumetric method： melt-like way,sample weight, volume of acidified et. It can complete the rapid determination of silicon dioxide content in manganese ore. Measurement Results consistent with the certified value and the analysis to satisfy the GB/T 1509- 2006 permission deviation request, The relative standard deviation of measurement results are less than 1%.
