# Chemiluminescence of luminol

Recently I have tried to perform an experiment with luminol and hydrogen peroxide (with potassium ferricyanide as the catalyst). Upon googling, I found two ways to conduct this experiment and was wondering which way is more suitable (because I have limited amounts of luminol and do not want to fail the experiment and waste luminol).

1st way: Preparing an alkaline stock solution of luminol and potassium ferricyanide and another stock solution consisting of hydrogen peroxide only.

2nd way: Preparing an alkaline stock solution of luminol and another stock solution consisting of hydrogen peroxide and potassium ferricyanide.
