Determination of Iron(II) using a derivative of 1,10-phenanthrolin

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 .
