In this study,X-ray fluorescence spectrometry(XRF)and inductively coupled plasma emission spectrometry(ICP-OES)were adopted to determine trace elements in petrole-um coke.The specimen was prepared by powder sample,the empirical coefficient method and the deduction of sulfur content matrix correction method were used,and the determination of Fe,Ni,V,Ca and Si by XRF possessed the characteristics of high accuracy,simple and rapid op-eration,which could meet the basic analysis needs of trace elements in common petroleum coke.The sample was pretreated by microwave digestion method,and the trace elements in pe-troleum coke were determined by ICP-OES.The influence of sampling amount and digestion temperature on the analysis results was discussed.The optimal analysis wavelength and limit of quantification of Zn,Co,Ni,Fe,Cr,V,Cu,Al and Na were determined.Determination val-ue of the trace elements by ICP-OES was close to that of XRF method,which provided data reference for petroleum coke products as petroleum coke materials to expand downsteam users.
