摘要：

Photodegradation of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) (I) in the presence of carbonates and bicarbonates was investigated. A quenching effect by carbonate and a much smaller by bicarbonate was found. The main photoproducts were 3-bromo-4-hydroxybenzonitrile (II) and 4-hydroxybenzonitrile (III) but traces of other unstable, unidentified products were detected by HPLC. The mechanism of carbonate quenching is discussed in terms of its reactions with photoreaction transients.
