Under ,acidic, conditions, decreasing the pH value had the most significant influence on NZVI-R3 with highest Fe loading for bromate removal; however, under ,alkaline, conditions, the most significant influence of pH was on NZVI-R1 with lowest Fe loading. The effects of co-existing anions N O 3 −, P O 4 3 − and H C O 3 − were also investigated.
