A new emerging hormone pollutants in aquatic environment

phthalic acid monoesters can lead to potential human health and ecological risks. In the present study

the adsorption performance of NXD-2（a hydrophilic bifunctional polymeric resin with tertiary amine groups）for mono-n-butyl phthalate (MBP) was studied by means of isotherms

thermodynamics

kinetics and dynamic column adsorption-desorption experiments. An analysis for sorption isotherms and thermodynamics showed that the adsorption of NXD-2 for MBP relied mainly on contribution of hydrogen bonding. The equilibrium adsorption capacities and adsorption rates increased with the increasing temperature in the range of 288—313 K. The results of continuous column adsorption demonstrated that at the condition of inflow with high concentration of MBP 300 mg·L-1，the removal efficiency of NXD-2 could make the MBP content in effluent lower the detection limit (10 mg·L-1) for first 100BV of effluent. Furthermore

NXD-2 was of good desorption performance

adsorbed MBP could be completely desorbed when adsorption volume reached 20BV. These results showed that NXD-2 could be an effective sorbent for the removal of phthalic acid monoesters in aqueous solution.
