ABSTRACT

3-hydroxy benzyl amino benzoic acid has been synthesized by the author in the laboratory which could be used successfully to estimate the amount of iron present in the water samples. This reagent-iron complex gave good absorption spectra with absorption maximum at 480 nm.  n-butanol was used as the solvent, a pH of 5.0 was maintained, the reagent concentration was chosen as 6.0 X 10-3 M and there was no interference of foreign ions.  With these standardized parameters, more than 90% recovery of added iron was found in the samples with the present method.  The value obtained with the present reagent was compared with standard reagent to be in good agreement, indicating the usefulness of the reagent for accurate spectrophotometric determination of iron in water samples.

Keywords: 3-hydroxy benzyl amino benzoic acid, Iron, Water samples.
