Ten trace elements including P,S,As,Sn,Cu,Sb,Pb,Zn,Cr and Cd in iron ore pellets has significant negative effects on the hot brittleness,corrosion resistance,and mechanical strength of steel,therefore,it is very important to strictly monitor their content in pellet raw materials. In this paper,an efficient and accurate inductively coupled plasma mass spectrometry( ICP-MS) method is established for the determination of the aforementioned elements. In the test,the microwave digestion was used for pretreatment of iron ore pellet samples to ensure complete dissolution of refractory mineral phases. As for the low sensitivity of sulfur in conventional ICP-MS,the collision/reaction cell technology conditions were optimized to eliminate polyatomic ion interferences and enhance the signal-to-noise ratio. In the detection of the remaining elements,the matrix interferences were effectively overcome through kinetic energy discrimination mode. Additionally,a mixed internal standard of Sc-In-Tb was used to correct the matrix effects and signal drift,ensuring the accuracy of the determination results. The results show that the correlation coefficients for all elements exceed 0. 999 0,with detection limits ranging from 0.02 to 1.56 μg/g,quantification limits from 0. 06 to 4.68 μg/g,precision between 1.95% and 4.12%,and spiked recoveries between 95.2% and 103.5%. The method studied in this paper can provide reliable technical support for quality control of iron ore pellets and risk assessment of residual elements in steelmaking.
