Özet:

 

A new spectrophotometric method is developed for the  determination of Fe(II) with 5-nitro-6-amino-1,10-phenanthroline  (NAF).  In this work, the effect of factors such as pH, amount of  reagent (NAF), reaction time and temperature were investigated.  The  method is based on the formation of a colored product between Fe(II)  and NAF. The reaction proceed quantitatively at 20 °C for 210 min in  acidic medium.  The absorption maximum was at 520 nm.  A linear  relationship existed between absorbance and Fe(II) concentration over  the range 0.1 m g/mL and 0.4 m g/mL. The molar ratio of Fe(II) to  the reagent was determined as 1:3.  The limiting concentration for  interference by Co(II), Ni(II), Cu(II), Zn(II), Mn(II), Al(III),  Ca(II) and Mg(II) cations are reported.
