| 英文摘要 | Phthalate esters are a group of plasticizers, which are commonly detected in china's soils and surface water. fenton reactions are naturally occurring and widely applied in the degradation of contaminants. however, limited research was considered the effects of clay minerals on contaminants degradation with (oh)-o-center dot oxidation. in this study, batch experiments were conducted to investigate the degradation of diethyl phthalate (dep) in fenton reactions in the presence of clay minerals, and the effects of clay type, fe content in clay structure. the results showed the clay adsorption inhibited total degradation of dep, and fe content in clay structure played an important role in dep degradation, including in solution and adsorbed in clay minerals. clay minerals with less fe content (<3%) quenched (oh)-o-center dot radical, while nontronite with fe content 19.2% improved (oh)-o-center dot radical generation and accelerated dep degradation in solution. the degradation of clay-adsorbed dep was much slower than dep in solution. six main products of dep degradation were identified, including monoethyl phthalate, phthalate acid, hydroxyl diethyl phthalate, etc. this study implied that phthalate ester's degradation would be much slower in natural water than expected in the presence of clay minerals.
