KBr O3 + Fe2 +组合对 4-硝基酚光化学降解的加速作用比单独使用 KBr O3 ,Fe2 +时所起作用都要强一些 .无光照下 ,K2 S2 O8+ Fe2 + ,KBr O3 + Fe2 + ,KMn O4 ,KIO4 + Fe2 + ,KIO4 + Mn2 + 对 4-硝基酚化学降解起加速作用 ,其中当 Mn2 + 浓度一定 ,KIO4 浓度逐渐增大时 ,KIO4 + Mn2 + 对 4-硝基酚化学降解的加速作用幅度最大 The accelerating effect of KBr O3 + Fe2 + on the photochemical degradation of 4-nitrophenol was stronger than that of KBr O3 and Fe2 + alone. In the absence of light, K2 S2 O8 + Fe2 +, KBr O3 + Fe2 +, KMn O4, KIO4 + Fe2 + and KIO4 + Mn2 + accelerated the chemical degradation of 4-nitrophenol. When the concentration of Mn2 + was constant and the concentration of KIO4 was gradually increased, the chemical degradation of 4-nitrophenol by KIO4 + Mn2 + Acceleration of the largest extent
