J. Prousek et M. Slosarikova, PHOTOCATALYTIC DEGRADATION OF 2,4,6-TRINI TROPHENOL (PICRIC ACID) IN AQUEOUS SEMICONDUCTOR DISPERSIONS, Chemicke listy, 90(10), 1996, pp. 829-832
Photodegradation of 2,4,6-trinitrophenol (picric acid) was studied by
means of aqueous semiconductors, such as ZnO and TiO2, as photocatalys
ts using both medium-pressure Hg lamp and sun light for irradiation. T
esting of the catalytic efficiency was based on removal of 2,4,6-trini
trophenol and decrease in chemical oxygen demand. Best results have be
en achieved with ZnO. The results were verified with the H2O2/UV syste
m which was also used in the study of 2,6-dinitrophenol degradation.
