“…There are many different chemical properties between them, such as different chemical structures and hydrophobicity. The molecular diameter of BPA is 0.43 nm, which is less than the value of EE2 (0.6 nm) [19]. The water solubility of BPA is about 50 times higher than that of EE2.…”

“…In addition, BPA has one more benzene ring with a hydroxyl group than EE2. The benzene ring can form π - π bond with the hard carbon part of SOM; therefore, the π - π bond formed between the hard carbon of SOM and BPA is stronger than that of EE2 [19]. The above reasons resulted in the higher adsorption capacity of BPA and significant inhibition to the adsorption of EE2.…”

Adsorption behavior of 17α-ethinylestradiol (EE2) in northern Taihu Lake sediment was analyzed by using batch equilibrium experiment. Freundlich isotherm could describe the adsorption thermodynamic behavior of EE2 in sediment. Sediment organic matter (SOM) contents had important impacts on the adsorption capacity for EE2. The pH values also influenced the adsorption capacity for EE2. Increase of pH value could decrease the EE2 adsorption, which might be due to the electrostatic repulsion between the anionic form of EE2 and sediments with negative charge under high pH values. Competitive effects of bisphenol A (BPA) on EE2 adsorption were further analyzed. The results showed that low concentration BPA did not have significant influences on EE2 adsorption. However, high concentration BPA could reduce EE2 adsorption, which might be due to the similar molecular diameter of BPA with adsorption sites and one more benzene ring with a hydroxyl group in BPA. These results provide primary information of EE2 adsorption in sediment-water system in Taihu Lake, which is useful for the environmental risk assessment and management of EE2 in studied area.

“…Pan and Xing (2010) reported the competitive adsorption of BPA and EE2 on carbon nanomaterials. Similar tests on the co-adsorption of BPA and EE2 were conducted by Li et al (2013b) on soils and Yu and Huang (2005) and Li et al (2014) on river sediments. In general, research on the competitive adsorption of EDCs on natural materials is largely limited.…”

“…Adsorption of EE2 in the concentration range tested can be fitted by the linear model and the Freundlich model, either with or without BPA. As a phenomenon of competitive adsorption (Li et al, 2013b), the 228 presence of BPA in the binary-solute system affected the adsorption of EE2. With the simultaneous existence of BPA, K d of EE2 in the linear partition model decreased by 7-18%, 230…”

“…Bisphenol A (BPA) is another typical EDC that had been widely employed previously as a plasticizer in industrial 3 production. Due to releases from various sources and insufficient removal from wastewater, EE2, BPA and other EDCs have entered rivers, lakes, soils and marine waters (Li et al, 2013b). Occurrence of EE2 in high abundance has been found in surface water (Peng et al, 2008), agricultural soil (Azzouz and Ballesteros, 2012), river and coastal sediment (Azzouz and Ballesteros, 2012;Zhang et al, 2009).…”

Adsorption of 17 α-ethyl estradiol with the competition of bisphenol A on the marine sediment of Hong Kong

The present experimental study was to characterize the adsorption behavior of 17 α-ethyl estradiol (EE2) onto marine sediment in both the single and binary solute systems. Stepwise spiking was innovatively performed to better understand the competition effects. Adsorption of EE2 on the marine sediment can be well fitted by the Freundlich model with an affinity coefficient (K) varying from 15.8 to 39.8L/kg. It was significantly influenced by SOM and the particle properties. Co-presence of BPA brought about a significant competition effect on the adsorption of EE2, leading to a reduced EE2 adsorption. The competitive effect imposed by EE2 to BPA, however, was even more serious owing probably to the large molecular structure and high hydrophobicity of EE2. The sediment sample with the highest SOM and SSA presented a mild competition effect, while the sediment with the lowest SOM and largest particle size exhibited the most serious competition effect.

Bisphenol-A (BPA), 17α-ethinylestradiol (EE2), and 4-nonylphenol (4NP) are endocrine-disrupting chemicals (EDCs) that are useful models for studying the potential fate and transport of EDCs in soil and water environments. Two alluvial soils with contrasting physicochemical properties were used as adsorbents for this study. The Zook soil material had more organic matter and clay than the sandy loam Hanlon soil material. Batch equilibrium experiments were performed to generate adsorption isotherms, to determine the adsorption parameters, and to assess desorption hysteresis. Adsorption of BPA to both soils followed an L-type isotherm, and 4NP adsorbed to both Hanlon and Zook soils exhibited S-shape isotherms. EE2 adsorbed to the Zook soil also followed an S-shaped isotherm, but EE2 adsorbed to the Hanlon soil showed an H-type isotherm. Overall, the Sips model fit the data well, with standard errors of prediction generally ≤6%. The adsorption affinity (K LF ) values were highest for 4NP, and BPA had the lowest hysteresis indices. The data suggest that BPA was most likely adsorbed by soil organic matter via hydrogen bonding involving its two phenolic groups. In contrast, isotherm shape, model affinity indices, lack of desorption, and molecular-scale characteristics led us to infer that 4NP was adsorbed largely by the retention of molecular clusters, perhaps in clay nanopores. Finally, the adsorption of EE2 exhibited different isotherm shapes for the two soils as well as intermediate affinity and desorption indices, suggesting that EE2 molecules could be retained both by soil organic matter and by clay.
