ABSTRACT

Diacetylmonoxime Isonicotinoyl Hydrazone is new chromogenic reagent for the determination of Ferrous Iron in trace quantities by direct spectrophotometric method . Iron (II) give yellow colour with Diacetylmonoxime IsonicotinoylHydrazone in ammonium hydroxideammonium chloride buffer medium PH 9 and λmax 355nm. The molar absorptivity and sandellís sensitivities are 3.83 X 104 L.mol-1.cm-1 And 0.002929 μg.cm -2. Ferrous iron forms coplex with the the reagent in 1:1 ratio. Microgram quantities of iron (ii) is determined in biological samples and cement sample.

Keywords: Ferrous Iron Diacetylmonoxime IsonicotinoylHydrazone, biologicalsamples, Cementsamples, Computed.
