Abstract

   Bisphenol A (2,2-bis(4-hydroxyphenyl) propane, BPA) is widely used as an ingredient in the manufacture of epoxy carbonate, poly carbonate and polyester styrene. Recently, some chemicals which are structurally similar to BPA (BPA related compounds: BPs) are coming to be used and it is reported that they have estrogenic activity on aquatic organisms. In this study, we determined the ability of Portulaca oleracea root and horse radish peroxidase (HRP) to remove 5 BPs (BPA, BPAF, BPZ, TDP and MBP) from water samples. When the initial BPs concentrations were 1 ppm, as same as BPA, BPZ and MBP were indicated removable ability at over 80% within 48hr, but BPAF could not be removed. The case of HRP, BPA, BPZ and TDP were indicated removable ability at over 45% within 60 min, but BPAF was removed 11.7 %.
