| Abstract: | In this paper, the deoxidizing reaction of Zine and oxalic acid in acidic medium is researched The glyoxylate ,which is generated in it, reacts with phenylhydrazine hydrochloride and generates glyoxy phenylhyarazone Whereas, after phenylhyarazone inversing diazo salt, it reacts with glyoxy phenylhyarazone generates pink azocompound Based on these reactions, the analytic method called spectrophotometric determination of microoxalate is presented Tested by simulation and water samples, the results are good and completely acceptable |
