Determination of Microgram Iron in High Purity titanium oxide by Extraction-Spectrophotometry |
| |
| Abstract: | After extracting the three-component complex-o-phenanthroline-Fe(Ⅱ)-picrate by 1,2-dichloroethane microgram iron in titanium oxide could be determied by spectrophotometry. Its apparant molar absorption coefficient was 1.22×105. This method, more sensitive and less interferential, has been used to analyze the iron content in high purity titanium oxides. |
