【摘要】Thispaper is focused on the selection of cosolvents in the remediation ofcontaminated soils. The aimof this study was to investigate thecombined effects of Triton X-100 (TX-100) and different cosolvents onthe solubilization behavior of 4,4′-dibromodiphenyl ether (BDE-15)and the washing of BDE-15 from a contaminated soil. 1H NMRspectroscopies were used to elucidate the interactions among TX-100,cosolvents, and BDE-15 in aqueous micellar solution. Results showedthat the solubility of BDE-15 was enhanced by the observedsynergismamong TX-100, BDE-15, and cosolvents, and theTX-100/dimethyl sulfoxide (DMSO) system exhibited the bestperformance in the solubilization of BDE-15. Similar synergism wasfurther evidenced in the washing of BDE-15 from a contaminated soil.With 10 % (v/v) DMSO and 6.4 mM TX-100 solution added, considerablesynergistic effect was achieved in TX-100/DMSO system, leading to thehighest removal efficiency (92.9 %) of BDE-15 from the soil, relativeto that of 67.3 % with TX-100 alone at the same concentration.
