[Influence of illuminance on the photo-reaction rate order of nitrofurazone solution].
OBJECTIVE
To explore the relationship between the illuminance and the observed order of reaction of photodegradation of nitrofurazone solution.


METHODS
Studying the observed order of reaction of photodegradation of nitrofurazone solution exposed to light with three illuminance values at three concentration values respectively.


RESULTS
The observed order of reaction of photodegradation increased with the decrease of concentration when the illuminance kept constant and, on the other hand, the observed order increased with the increase of illuminance when the concentration kept constant.


CONCLUSIONS
The observed order of reaction of photodegradation of nitrofurazone solution depends on both the concentration of the drug and the illuminance of the incident light.
