采用干法灰化对加氢裂化原料油进行处理,制备原料油样品水相测定溶液。用原子吸收光谱法对样品中的铁、镍、钒进行了测定,对测定过程中共存元素的干扰进行了研究,采用加镧抑制剂的方法消除干扰。结果表明,各元素的回收率在95%～104%,相对标准偏差均小于5%。
採用榦法灰化對加氫裂化原料油進行處理,製備原料油樣品水相測定溶液。用原子吸收光譜法對樣品中的鐵、鎳、釩進行瞭測定,對測定過程中共存元素的榦擾進行瞭研究,採用加鑭抑製劑的方法消除榦擾。結果錶明,各元素的迴收率在95%～104%,相對標準偏差均小于5%。

The hydrocracking raw oil treated with dry-ash process was dissolved in water solution.Iron,nickel and vanadium in the solution were determined by atomic absorption spectrometry.The interference of coexisting elements was measured and eliminated by the addition of lanthanum-based inhibitor.The results of a precision experiment showed that the recovery was 95%~104% and the relative standard deviation（RSD） was less than 5%.
