Determination of Elemental Al in Slag Washing Material
Due to the excellent desulfurization effect of CaO-Al2O3-SiO2 slag system,its main components are elemental Al and C.To quantitatively analyze the content of elemental Al,the sample was dissolved in FeCl3 aqueous solution ammonium chloride solution to effectively separate elemental Al from Al2O3.The experimental results indicate that the error of the experimental data(mass fraction)for measuring elemental Al is within 0.30％.
