摘　　要：本文建立了用于定量分析分段压裂的磁性纳米示踪剂的电感耦合等离子体质谱(ICP-MS)方法,考察了定量分析时存在的干扰。结果表明,分析元素具有良好的线性关系,相关系数大于0.999,检出限在0.18~0.0022μg/L之间,加标回收率为101.1%~104.8%,相对标准偏差(RSD)为1.3%~3.3%。磁性纳米示踪剂的回收率稳定且高于90%,表明该方法满足对磁性纳米示踪剂定量分析的要求。A method for quantitative analysis of magnetic nanotracers used in staged fracturing by inductively coupled plasma mass spectrometry(ICP-MS)was established.The interference in the quantitative analysis was studied.The results showed that the analytical elements exhibit good linear relationships,and the correlation coefficients(R^(2))were higher than 0.999.The limits of detection were 0.18-0.0022μg/L,the recoveries were 101.1%-104.8%,and the relative standard deviations(RSDs)were 1.3%-3.3%.The recoveries of magnetic nanoparticle tracers were stable and higher than 90%,showing that this method can meet the requirement of quantitative analysis of magnetic nanotracers.
