SPECTROPHOTOMETRIC DETERMINATION OF IRON IN SOIL SAMPLES
Neeru Gakkhar*, Rashmy Nair and Chandni Jain
ABSTRACT
A rapid, simple and less expensive spectrophotometric method has been described for determination of iron content in soil samples. In the present study three samples of soil collected from Jaipur city have been analysed. Iron content was determined spectrophotometrically in the form of orange- red complex of Fe(II) and 1,10 phenanthroline. The absorbance is measured at 510 nm wavelength. A calibration curve was found to be linear at the concentration range of 0.2 mg/l to 1.8 mg/l. This method was successfully applied for the determination of iron in water and food samples.
