摘要：Colorimetric determination of vanadium in foods with N-cinnamoyl-N-(2, 3-xylyl) hydroxylamine (CXA) was studied. Vanadium was extracted effectively with CXA in C₆H₆ from 1-4N HCl acidic solution of digested sample. This reagent proved to be more sensitive and more selective than both of N-benzoylphenylhydroxylamine and N-benzoyl-o-tolylhydroxylamine which have been recommended as a chelating reagent for colorimetric determination of vanadium. By using CXA, vanadium in various foods could be determined with the recovery of 91.2-103.2% and the coefficient of variation of 2.0-5.5%.
