Similar properties of Fe2+and Fe3+ during the photochemical Reaction of 4-Chlorophenol

Under the shining of light, Fe2+, Fe3+ concentration variation in 20mg/L4-CP + lmg/L Fe2+system A)and 20mg/L4-CP-f-lmg/L Fe3+ (system B)were studied. By IC method, Fe2+ and Fe3+ were determined out in system A simultaneously, there was similar case in system B too. So Fe2+ and Fe3+ showed some similar properties during the photochemical reaction of 4-chlorophenol.
