| Abstract: | Trace amount of chromium was first converted quantitatively to volatile chromium chelates such as chromium(III) acetylacetonate, Cr(acac)1, chromium(III) trifluoracetylacetonate, Cr(tfa)3, and chromium(III) hexafluoroacetylacetonate, Cr(hfa)3, and the chelate solution was then analyzed by gas chromatography. It was found that Cr(tfa)3 is the most suitable chemical form for this purpose. The method was profitably applied to the determination of chromium(III) incorporated in the six kinds of commerical products of potassium Chromate. |
