Different brands of biscuits were studied for the presence of phosphorus, glucose and Iron using Electro analytical technique. UV- Visible spectrophotometric analysis enabled to know the composition of certain metals. The sample solutions were prepared by ashing and using 6N HCl.In the present study, absorbance measurements were made in the range, 500nm to 850nm. For the analysis of iron, the samples were made to react with 1, 10 phenanthroline and hydroxyl amine hydrochloride to give a red coloured complex which was measured at 510nm. The presence of phosphorus was known by the blue coloured complex formed when the samples were treated with ammonium molybdate and absorbance measurements made at 810 nm. By treating the samples with alkaline cupric tartarate and phospho molybdic acid, blue oxides of molybdenum were formed and absorbance measurements were made at 640nm for the presence of glucose. This method demonstrated good reproducibility and was found to be simple, accurate and less time consuming.
