[A rapid method for the determination of hydrogen peroxide concentration]

Area of Science:

• Analytical Chemistry
• Spectroscopy

Context:

• Accurate quantification of hydrogen peroxide is crucial in various industrial applications.
• Existing methods may be time-consuming or costly.

Purpose:

• To develop a simple, rapid, and cost-effective spectrophotometric method for hydrogen peroxide determination.
• To establish optimal reaction conditions for the assay.

Summary:

• A spectrophotometric method was developed based on the reaction between ceric sulfate and hydrogen peroxide in an acidic medium.
• The method measures the absorbance change at 480 nm, corresponding to the reduction of tetravalent cerium to trivalent cerium.
• Optimal conditions include 0.5 mol/L H2SO4 and a 3.0-minute reaction time, yielding excellent precision (RSD = 0.31%) and accuracy (RSD ≤ 0.91%).

Impact:

• Provides a highly sensitive and accurate method for hydrogen peroxide quantification.
• Suitable for rapid industrial analyses due to its simplicity, speed, and low cost.
