| Abstract: | in this paper, a method is described on the quantitative determination ofVanadium and Nickel in the extract of source rocks using formed filter paper method by Xray fluorescence spectrometry. Metal-organic compounds of Vanadium and Nickel were used to prepare standard samples, formed filter paper was adopted as support material of standardsamples and specimens, dripping method was was used to prepare sample pieces, and transmission method was used to reduce background scattering intensity and detection limit. The experimental results indicate that the precision is better than 5%, the standard recovery is in the range of 97-- 106%, and the method is simple, rapid and practical. |
