COLORIMETRIC DETERMINATION OF IRON WITH DIACETONE ALCOHOL - A NEW ANALYTICAL REAGENT

The potential of diacetone alcohol as a new analytical reagent has bee n investigated for numerous cations. These studies have provided basis cf a new and simple method for the spectrophotometric determination o f Fe(II). The reddish brown coloured complex of Fe(III) with this new reagent at the natural pH (1.33) obeys Beer - Lambert's law over usefu l range of iron concentration (25-150 ppm). The visual Limit of identi fication is 5 parts of ion per million parts of solution. This reagent may also be used to differentiate between ferrous and ferric ions.
