Chimiluminescence

Our project consists in replacing the bulbs of the lamps, which are for the most part sodium lamps, with bulbs which recreate light chimiluminescence.

So we studied how it would be better for our environment.
It is important to know that the light produced by our lampposts “destroys” the fauna and flora. After much research we realized that what we will handle to obtain are blisters and harmful or toxic products, but only if they come into contact with nature.
We carried out about twenty experiments in order to find the ideal time and to measure the intensity of the light produced.

For this we mixed 0,1 g of luminol with 150 ml of soda and 2,5 ml of hydrogen peroxide then we mixed part of this solution which we called the luminol solution with a catalyst, So we tried several catalysts and at different amounts each time.
The best time we got was 7min25s.
