Abstract The purpose of this investigation was to study the reactivity of 1, 2, 3- cyclohexanetrione trioxime with inorganic ions, in particular the cobalt(II) ion which reacts with it to give a stable yellow complex. This complex does not give an absorption maximum, but shows increased absorbance from 575 to 375 m mu. The wave length selected for this study was 400 m mu, since the reagent shows essentially no absorbance at this value. The reaction is carried out in a solution with the pH adjusted between 3 and 4. The optimum concentration range for cobalt in the colorimetric procedure developed is 1 to 4 ppm. Of the diverse ions checked, nickel, iron and copper interfere. A preliminary study has been made of this reagent for the determination of these three elements. (auth)
