| Abstract: | In this paper,the conventional method which determination of trace iron by sulfosalicylic acid spectrophotometry was improved.The linear range was downward extended by the differential spectrophotometry method.The calibration curve was linear in the range of 1～20 μg/25 mL(R=0.999) .The method was used to determinate the content of iron in running water.The returns-ratio was about 89.8%～96.0%. |
