  • 摘要: 为了对原油中金属元素含量进行分析,利用激光诱导击穿光谱技术分别采用Na光谱的积分强度、峰值强度作定标曲线对高温灼烧后的原油中的Na进行了定量分析。实验中选取Na Ⅰ 588.995nm,Mg Ⅰ 383.230nm,Al Ⅰ 308.215nm,K Ⅰ 404.414nm,Ca Ⅰ 364.441nm,Fe Ⅱ 273.955nm作为分析线对原油样品灼烧后的6种元素进行分析,测得其质量分数分别为0.0592,0.0029,0.0212,0.0019,0.0072,0.1686,并得出了定标曲线的线性相关系数及检出限。结果表明,选用积分强度作定标曲线效果更好;激光诱导击穿光谱技术测量结果与X射线荧光光谱技术对Na的测量结果相对误差为6.28%;激光诱导击穿光谱技术可应用于原油中金属元素含量的测量。
