I'm performing a electrochemical experiment, which should produce hydrogen peroxide, what techniques should I employ to reliably detect it from the solution, also what will be the best way to quantify the production?
You can determine the concentration of hydrogen peroxide by spectrophotometric measurements at 407 nm with the aid of titanium IV solution (https://doi.org/10.1016/j.elecom.2016.08.007), or by electrochemical measurements with the aid of platinum electrode and phosphate buffer (https://doi.org/10.1016/j.electacta.2020.136048).

1. As a general rule, the classical technique consists in direct measurement using UV vis., Absorbance at 240 nm of the molecule H2O2.
2. introduction of ferrous iron, that is to say, the reaction of peroxide with ferrous iron and H2O2 via the measurement of the absorbance of the solution at 550 nm.
3- Redox titration of hydrogen peroxide by potassium permanganate
Other methods are available in the literature.

If your solution is not colored the simplest and reliable method is to convert H2O2 into the yellow colored Ti(IV)-peroxide complex. Tons of literature. the simplest protocol is in https://arxiv.org/ftp/arxiv/papers/1604/1604.08803.pdf

Dear Satadru Chakrabarty
You can detect hydrogen peroxide using different methods,
1- Spectrophotometer at wavelength 240 nm
2- Hydrogen Peroxide Colorimetric/Fluorometric Assay Kit
3-Iodometric or Permanagatomeric titration techniques

from above link you can know recent methods to determine H2O2
Dear Oday Hasan Ali Al-Jammaas ' "recent methods?" The review is 8 years old!
Dear Ryan Sheikh , plz be specific. What are "coloremetric or colorless reactions?"
Each answer must be informative. Otherwise, it can be considered as an unethical attempt to increase the RG score.
