Abstract: Taking tap water as the raw water,the adsorption efficiency and kinetics of activated granular carbon in estrogen removal were studied by adding estrone(E1),17β-estradiol(E2) and 17α-ethynylestradiol(EE2).Resultsindicated that estrogens in tap water could be removed by activated adsorption quickly and efficiently. Adsorption equilibration was reached after contact for 10 min. The adsorption equilibration was related to the estrogen initial concentration. At initial concentration of 500 ng/L,the removal efficiencies of E1,E2 and EE2 were 74.7%,89.5% and 82.8%,respectively. In presence of E1,E2 and EE2 simultaneously,the adsorption of E2 by activated carbon was deteriorated significantly(at initial concentration of 500 ng/L,the adsorption equilibration concentration increased from 44.65 to 195.03 ng/L),however,the adsorption of E1 and EE2 was not affected. The adsorption isotherm data obtained from different initial concentrations could be well explained by the Freundlich isotherm equations.
