الخلاصة

The research is included determination of Fe(II) via its reaction with 1,10-phenanethroline to form light-red complex which is absorbed at λmax=510 nm. Home-made flow injection valve is designed with two loading loops, L1 and L2. A series of studies are conducted represented by fixing physical and chemical optimum conditions, dead volume, repeatability, dispersion coefficient, construction calibration graph, and application of the method. The dead volume is zero for the system which it has high repeatability (n=8) with RSD and SD 0.6 and 0.05 respectively. The dispersion coefficient is 1.68 at the concentration 10 ppm. The range of measurements of calibration graph is (0.05-18.00) ppm with limit of detection (S/N=3) 0.05 ppm.
