Summary
A new spectrophotometric method accurately determines selenium using a redox reaction with ferrocene. This sensitive technique is effective for analyzing selenium content in materials like copper metal.
Area of Science:
- Analytical Chemistry
- Spectrophotometry
- Redox Chemistry
Background:
- Accurate determination of selenium is crucial in various industrial applications.
- Existing methods for selenium analysis may lack sensitivity or require complex procedures.
Purpose of the Study:
- To develop a sensitive and reliable spectrophotometric method for selenium determination.
- To validate the method's applicability for analyzing selenium in copper metal.
Main Methods:
- A redox reaction between selenious acid and ferrocene in hydrochloric acid was employed.
- Iron(III) generated was quantified using 1,10-phenanthroline.
- Spectrophotometric measurements were performed at 512 nm.
Main Results:
- The method demonstrated high sensitivity with an apparent molar absorptivity of 4.23 x 10^4 L.mol⁻¹.cm⁻¹.
- A relative standard deviation of 1.1% was achieved for 20 µg of selenium.
- Successful determination of selenium in copper metal samples was accomplished.
Conclusions:
- The developed spectrophotometric method offers a sensitive and accurate approach for selenium quantification.
