Abstract orange peel, pomegranate peel has a high medicinal value, especially suitable for deep processing, made from a variety of drugs, have a certain impact on the iron content of its medicinal value, and therefore iron, orange peel, pomegranate peel the detection of the development and utilization of orange peel, pomegranate rind of great significance. In this experiment, the product as a sample in the pretreatment of orange peel and pomegranate peel, using phenanthroline spectrophotometry in the range of ph = 2 ~ 9 hac-naac, buffer; accurately draw the sample solution 6ml in 25ml cuvette, add 10% hydroxylamine hydrochloride 2ml of 0.15% phenanthroline 2ml 1mol / l sodium acetate solution 5ml diluted with water to the mark at rest 12 hours, measured absorbance at 510nm at
Keywords orange peel granatum iron content by spectrophotometry.
