| Abstract: | Adsorption of bisphenol A(BPA) onto sediments(natural surface coatings),which were modified by sodium dodecyl benzene sulfonate(SDBS),TX-100 and cetyltrimethylammonium bromide(CTMAB),was investigated,and the enhanced-control of CTMAB on BPA adsorption and relative contributions of surface adsorption and partition of BPA were also analyzed.Results showed that surfactants had promoted BPA adsorption to sediments(natural surface coatings) ranking as CTMAB,TX-100 and SDBS,and the removal efficiencies of BPA fro... |
