| Abstract: | Summary A universal method for quantitative analysis of twelve elements in low-alloy steels is described. The samples are digested in a mixture of sulfuric-/nitric acid/ammonium peroxodisulfate. Si, Mn, P, Cu, Al, Ni, Cr, Mo, V, Ti, Co, As are determined in solution by ICP-AES. The procedure was tested with NBS and BCS reference samples. The analytical results are in good agreement with the certified values. With slight modifications, the method is applicable to the analysis of high-alloy steel samples. |
