Fe (II) forms a coloured ternary complex with SCR in presence of 1,10-Phen which have molar absorptivity of 3.56x104 mole-1 cm-1 at pH 5.0 and lmax 520 nm. The complex contains three molecules of 1,10-Phen coordinated to Fe (II) ion and one molecule of SCR through ion association giving the overall formula Fe (II) (SCR) (Phen)3. Beer’s law range is 0.0223-1.6084 ppm and Sandell’s sensitivity 0.0045 n/cm².
