The removal effect of 2,4,6trichlorophenol (TCP) by five kinds of activated carbon (GAC0、GACH、GACF、GACF1M1、GACF1M3)were investigated. And it was found that the adsorption capacity was 160,178,207,194 and 238 mg/g, respectively. With the further study of GACF1M3’s performance, it was shown that adsorption capacity increased with initial concentration increasing, and decreased with temperature increasing. When the temperature was changed from 30℃ to 45℃, the removal rate would reduce slightly. The dosage increased from 10 mg to 500 mg, the removal effect improved significantly. Acidic condition was more favorable for the adsorption of TCP. Upon the analysis of the reaction kinetics, it was found that the reaction could be simulated with pseudosecondorder kinetic model. With XRD and SEM, the main metal oxide composites of GACF1M3 were Fe3O4、Mn3O4、FeOx(MnO)1-x.
