摘要
采用电感耦合等离子体原子发射光谱(ICP-AES)分析技术,同时测定了高钢级管线钢中的硅、锰、磷、铬、镍、钼、铌、钒、钛、铜、铝等元素。对试样溶解方法、元素分析谱线、仪器分析参数等因素进行了研究,选择了最佳的分析谱线及合适的仪器工作条件。方法应用于钢铁标准样品中各元素的测定,测定值与认定值吻合,精密度小于3%。方法应用于实际样品分析,测定了X90、X100管线钢中的元素含量,结果满意。
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.
