ICP-AES法测定高炉渣中MgO,Al_2O_3,SiO_2,TiO_2含量

Determine the Content of MgO,Al_2O_3,SiO_2,TiO_2 in Blast Furnace Sediment with the Method of ICP—AES

采用电感耦合等离子体原子发射光谱(ICP-AES)法测定高炉渣中Mg,Al,Mn,Ti的含量,选取适宜的仪器测定参数和分析谱线,采用HCl-HNO_3-HF-HClO_4的混合酸体系,可以使样品完全溶解。在选定的条件下,回收率达97%～108%。

Adopt the method of inductance coupling plasma atomy emission spectrum to mensurate the content of Mg, Al, Mn, Ti in blast furnace dregs, choose the apparatus parameter and analyzing register in order.The experimentation result indicate that the mix acid system can ertirety dissolve the sample.Under the fix condition, the reclaim rate is between 97% and 108%.
