摘　　要：在实验条件下,Mn2+/Fe2+/Cu2+/Zn2+/Al3+/La3+,KMnO4/K2S2O8/KBrO3/KIO3/KIO4对间苯二酚光化学降解起加速作用,且随浓度增大而增强.KBrO3+Fe2+,KIO4+Mn2+对间苯二酚光化学降解的加速作用更为显著.无光照时,KMnO4,K2S2O8/KBrO3+Fe2+,KIO4+Mn2+/Fe2+都能够使间苯二酚立刻发生化学降解,尤其以KMnO4,KIO4+Mn2+的作用更为显著.Under experimental conditions, Mn2+/Fe2+/Cu2+/Zn2+/Al3+/La3+, KMnO4/K2S2O8/KBrO3/KIO3/KIO4 can accelerate the photochemical degradation of resorcinol, and with the increase of concentrations of these metal ions and oxidants, this acceleration effect also increases. Cooperative effects of KBrO3+Fe2+, KIO4+Mn2+ on the photochemical degradation of resorcinol are more striking. Without illumination, KMnO4, K2S2O8/KBrO3+Fe2+, KIO4+Mn2+/Fe2+ can lead resorcinol to be oxygenated at once, the effects of KMnO4 and KIO4+Mn2+ are more striking.
