Abstract: According to Monte Carlo mechanism and random process theory,the mechanism of phenol degradation on titanium electrode was simulated. The effects of degradation time,initial concentration of phenol,electrode performance and intermediates on the process of degradation were determined. The results indicated that the phenol concentration is decreasing and becoming steady during the degradation process,if increase the initial concentration,the degradation rate is also increased at the beginning of reaction process,the electrodes with high performance strongly affect the first step of degradation by reducing the residence time of intermediates,the whole process and the productions of second step are primarily controlled by the first step of reaction,and the effect of second step on the whole process is minor.
