摘要：Frequency detection and environmental risk of Tetrabromobisphenol A （TBBPA）in aqueous system attracted many concerns. Nevertheless, mutual interactions between TBBPA and natural or synthetic chemical materials has not be clearly revealed. In this study, influential factors, adsorption behavior and mutual dynamism of active carbon (AC) and TBBPA were comprehensively explored. It was found that chemical sorption efficiency of AC reached more than 90%. The adsorption behavior can be depicted by Langmuir and Freundlich isotherms, whose kinetic could be well described by pseudo-first-order kinetic model. The chemisorption of AC is mainly single molecular layer mode for TBBPA adsorption, during which presence of SO42-, HCO3- and humic acid significantly inhibited TBBPA sorption capability. Proper temperature and pH promoted the adsorption efficiency of TBBPA. The obtained results demonstrated that AC adsorption is one feasible and effective technique for enhanced treatment technique for TBBPA containing wastewater.

The chemisorption of AC is mainly single molecular layer mode for TBBPA adsorption, during which presence of SO₄^2-, HCO3^- and humic acid significantly inhibited TBBPA sorption capability. Proper temperature and pH promoted the adsorption efficiency of TBBPA. The obtained results demonstrated that AC adsorption is one feasible and effective technique for enhanced treatment technique for TBBPA containing wastewater.
