Title: Process for the quantitative and qualitative analyses of aldehydes and ketones in aqueous solutions

Abstract: Trace amounts of carbonyl compounds, I, in aqueous solutions are analyzed by mixing the aqueous solution with radioactive derivatives of ammonia, II. Carbonyl compounds stoichiometrically react with derivatives of ammonia as follows ##EQU1## The weight of the parent compound, I is calculated from the radioactivity of the product, III, and the specific activity of II. The product is separated from the reaction mixture by chromatography or electrophoresis. The identity of I, if unknown, can be determined from the characteristic chromatographic or electrophoretic mobility of the derivative, III. The sensitivity of the method is determined by the specific activity of the radioactive chemical, II. Thus, if II contains 100 micro curies per micro mole, the process would detect 10.sup.-12 mole of carbonyl compound.
