| Abstract: | A derivative spectrophotometic method is described for the determination of iron in foods,using phenantroline as chromophoric reagent.The peak area of the 2nd derivative absorption spectrum from 505.11 to 521.77nm is proportional to iron concentration.Compare with other methods,its accuracy is higher,and result is more satisfactory. |

| Keywords: | Derivative Spectrometry Iron Phenantroline Peak Area. |
