| Abstract: | Make a experimentation on three facets of determination iron in water using phenanthroline spectrophotometric method. Three facets refer to the pure water,the hydrochloric acid and the buffering solution( using the sodium acetic acid buffering solution instead of the ammoonium acetic solution).In this way , the blank value may reduce to 0.008. |
