摘　　要：本文通过实验证实,称样量为1 g,稀释10倍,以铑作内标元素,不进行基体分离,通过质量数选择消除质谱干扰,采用稀释法、内标法、标准加入法绘制校准曲线消除基体效应,可实现电感耦合等离子体质谱法对高纯铪中铁含量的测定。In this paper,it is confirmed by experiments that the sample weight is Ig,diluted 10 times,rhodium is used as the internal standard element,without matrix separation,mass spectrum interference is eliminated through Mass number selection,and matrix effect is eliminated by using dilution method,internal standard method,and standard addition method to draw calibration curve,which can realize the determination of iron content in high-purity hafnium by Inductively coupled plasma mass spectrometry.
