Determination of Multi-Elements in High Grade Pipeline Steel by Inductively Coupled Plasma Atomic Emission Spectrometry
In this paper, by using inductively coupled plasma atomic emission spectrometry(ICP-AES) analysis, a method for simultaneous determination of Si, Mn, P, Cr, Ni, Mo, Nb, V, Ti, Cu and Al in high grade pipeline steel have been studied. The experiment factors including the method for dissolving sample, spectra of analyzed element and instrument parameters have been investigated. This method was applied to determine the elements in steel standard sample and the results were con-sistent with the certified values. The relative standard deviations (RSDs, n = 10) for all elements were smaller than 3%. The proposed method was successfully applied to X90 and X100 high grade pipeline steel practical samples determination with satisfactory results.
