AB  - Bisphenol A is a chemical with hazardous health effects that is largely used in 
      the manufacture of extensively used products including adhesives, plastics, 
      powder paints, thermal paper and paper coatings, and epoxy resin, and is reported 
      to exist in nature in an accumulative manner. In this study, both pristine and 
      boron-doped multiwalled carbon nanotubes (MWNTs) were employed as filtration and 
      electrochemical filtration materials, resulting in a significant removal of 
      bisphenol A with identical performance for both MWNTs types. It was shown that 
      the presence of salt is not critical for the greatest contaminant removal 
      efficiency, likely due to the vital role of other electroactive species (e.g. 
      reactive oxygen species). Near complete removal of 1 mg L(-1) bisphenol A at 2 
      and 3 V of applied DC potentials was achieved, indicating that the 
      electrochemical filtration process is voltage dependent at both 2 and 3 V. 
      Increasing the residence time by 7.4 fold (from 2.0 to 14.9 s) resulted in a 
      significant removal of bisphenol A and its toxic byproducts, up to 424 min of 
      electrochemical filtration time at 3 V of applied potential. Based on these 
      results, electrochemical filtration using MWNTs is considered a promising 
      technology for the removal of the accumulative bisphenol A and the reduction of 
      its hazardous effects in waters.
