| Abstract: | A method has been developed for the determination of trace iron, based on the discoloration of methyl blue by hydrogen peroxide in H 2SO 4 solution under the catalysis of Fe(Ⅲ). The linear range of the method is 0.0192 -0.0660 μg·mL -1 with a detection limit of 8.01×10 -10 g·mL -1 . The method has been applied to the determination of trace Fe(Ⅲ) in water samples with satisfactory results. |
