摘要

The present invention relates to a method for analyzing calcium oxide in steel by-product slag by atomic absorption spectroscopy. As described above, in the method of the present invention, the sample is directly nickel-free without first treating the slag sample with a solvent such as hydrochloric acid or nitric acid. Into a slag sample using a mixed flux (Na 2 CO 3 : Na 2 O 2 = 3; 1), which has a strong bonding force, and thus CASO 4 or Ca 3 (PO 4 ) 2 , which inhibits the formation of neutral atoms. By decomposing to form sodium sulfate and sodium phosphate to increase the atomization of calcium to be analyzed in the AAS analysis, the analysis time is shortened, and the accuracy of the analysis can be secured.
