A Rapid Method for the Determination of Hydrogen Peroxide Concentration
The present paper reported a spectrophotometry for the determination of hydrogen peroxide concentration. It is based on the reaction between ceric sulfate and hydrogen peroxide in an acidic medium, in which orange tetravalent cerium is converted to colorless trivalent cerium that causeds the change in absorbance. According to the quantitative relationship between ceric sulfate and hydrogen peroxide, the hydrogen peroxide concentration can be calculated. The selected conditions were as follows: detection wavelength of 480 nm, H2SO4 concentration of 05 mol·L-1, and reaction time of 30 min. The results showed that the method has an excellent measurement precision (RSD=0.31%) and accuracy (RSD≤0.91%) for the quantification of hydrogen peroxide. The present method is simple and rapid, with high detection sensitivity and low cost. It is suitable for use in rapid industrial analyses.
