Roles of functional groups and irons on bromate removal by FeCl3 modified porous carbon

Ferric chloride modified lotus stem-based porous carbon (FeCl3-LSPC) was synthesized for the removal of bromate from aqueous solutions. The adsorbent characterization indicated that the BET surface area and pore volume were enlarged by the modification of FeCl3, at the same time, the reductive functional group of C-OH was enhanced in the FeCl3-LSPC. The FeCl3-LSPC exhibited greater bromate removal performance in a wide pH range compared to other...
