【摘要】 本文以硝酸钙为钒的基体改进剂,用石墨炉原子吸收光谱测定了钒的特征质量,并将实验值与L’vov提出的特征质量计算方法算出的理论值进行了比较,两者基本吻合。在此基础上用绝对分析法测定了催化剂及重油中的钒的含量,分析结果与化学法测出的结果无显著差异。更多还原

【Abstract】 In this paper, theoretic calculation of characteristic mass of vanadium under experimental condition is performed by applying L’vov’s equation. The theoretical characteristic mass coincides with the experimental characteristic mass which was obtained by STPF using calcium nitrate as modifier. The developed method was applied to the determination of the content of vanadium in catalyst and heavy oil, and the determined values were in a good agreement with that obtained by chemical method.更多还原
