研究了在氯化铁和氯化锰存在下，溴二腈（3,5-二溴-4-羟基苯腈）的光降解。与缓冲液或水溶液相比，这两种阳离子都能提高溴腈的光降解率，但在较低的pH（< 5.0）下效果更为显著。两种阳离子的混合比在相同浓度下的单独溶液更大程度地提高溴腈的分解率。这种效果取决于铁锰比。
Photodegradation of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) (I) in the presence of ferric chloride and manganese chloride was investigated. Both cations were found to increase the photodegradation rate of bromoxynil as compared to that in a buffer or water solution, however the effect was found to be more significant at a lower pH (< 5.0). Mixtures of both cations increased the decomposition yield of bromoxynil to a greater degree than independent solutions at the same concentration. The effect is dependent on the Fe/Mn ratio.
