Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.

In catalyst, oxygen produced from H202
With sodium hydroxide, luminol Dianion is formed
The oxygen reacts with luminol dianion
This product is very unstable, so decomposes to 5-aminophathalic acid
As the exited state, 5-aminophathalic acid relaxes to ground state
Excess energy is emitted as blue light
Alkaline luminol, H2O2 solution is used on detecting NO2
The presence o
need a catalyst to accelerate the process. The catalyst in this case is the iron in hemoglobin . If hemoglobin and the luminol mixture come in contact, the iron in the hemoglobin accelerates a reaction between the hydrogen peroxide and the luminol. In this oxidation reaction, the luminol loses nitrogen and hydrogen atoms and gains oxygen atoms, resulting in a compound called 3-aminophthalate.
