摘      要:The kinetics of heat-facilitated persulfate oxidation of p-chloroaniline(PCA) in aqueous solutions was measured at five different temperature conditions and at four different oxidant *** PCA degradation was found to follow a pseudo-first-order decay model when the persulfate was *** pseudo-first-order rate constants of PCA degradation by persulfate(50 mmol/ L) at pH 7.0 are 0.12×10^-4,0.28×10^-4,0.43×10^-4,0.83×10^-4,1.32×10^-4 s^-1 at 10,20,30,40 and 50℃,respectively. Under the above reaction conditions,the reaction has activation energy of 49.97 kJ/*** observed rate was found to be function of temperature and oxidant *** temperature and increasing persulfate concentration can significantly accelerate the PCA degradation.
