摘要：

In this research, adsorption of two estrogens, namely, 17β-estradiol (E2) and 17α-ethynylestradiol (EE2), by graphene nanosheets with different reduction degrees (rGOs) were investigated;and the effects of solution chemistry, such as natural organic matter (NOM), pH and ionic strength (IS), on the E2 and EE2 adsorption behaviors were also examined. Results indicated that adsorption abilities of estrogens increased with increasing the reduction degree of rGOs;the π–πstacking interaction could be considered as a predominant interaction to the enhanced adsorption capacities...
