Abstract:
In this study we used a very sensitive , highly selective
spectrophotometric method for determination of iron by using a
derivative of 1,10-phenanthroline.
Factors such as the low cost of the instrument ,easy ,handling lack of
requirement for consumable and almost no maintenance have caused
spectrophotometry to remain a populer technique ,particularly in
laboratories in developing counties.
5-nitro 1,10-phenanthroline forms octa hedral complex with intense red
color with iron(II) that may exploited to determination iron
concentration in the rang of part per million .
The experiment do in room temperature and pH 2.4 , in ethanol , the
suitable wave length to the complex was found 580 nm.
The strongly advocate that be for the analysis process we must separate
any element which may be formed any interference with iron complex
such as zinc .
