The feasibility of using granular ferric hydroxide (GFH) with zero-valent iron (Fe(0)) for its potential utility in enhancing nitrate reduction was investigated. The addition of 10gL −1 GFH to 25gL −1 Fe(0) significantly enhanced nitrate removal, resulting in 93% removal of 52.2mg-NL −1 in 36-h as compared to 23% removal with Fe(0) alone. Surface analyses of the reacted Fe(0)/GFH...
