      abstract = {This study investigated the spectroscopic determination of iron in soil samples using 1,10-phenanthroline as a complexing reagent. The method is based on the formation of an intensely coloured iron (II)-1,10-phenanthroline complex, which was quantified by measuring its absorbance at 510 nm using a UV-Visible spectrophometer. A series of iron (II) standard solutions was prepared, and a calibration curve was established in accordance with the Beer–Lambert law. The resulting calibration equation was used to determine the concentration of soluble iron in four unknown soil samples. The measured absorbance values for Samples A, B, C and D were 0.32, 0.30, 0.24 and 0.24, corresponding to iron concentrations of 0.611, 0.570, 0.450 and 0.450 ppm, respectively. Sample A recorded the highest iron concentration, while Samples C and D had the lowest concentrations. The results demonstrate the applicability of the 1,10-phenanthroline method for the quantitative determination of iron in soil samples.},
