Abstract—This research aims to synthesizes nano-zero valence iron coated on activated carbon (nZVI/GAC). Characteristics of the synthesized materials were investigated. The morphology was examined using scanning electron microscope (SEM). The synthesized material was used as the adsorbent material for atrazine removal. The comparisons of removal efficiency were studied in both cases of adsorption and Fenton-like reaction. The results showed that nZVI/GAC adsorbent materials can achieved 96% atrazine removal efficiency compared to GAC adsorption. The factors influencing the atrazine removal were the amount of material and the initial concentration of atrazine. Mixture ratios of Fe/GAC were also investigated for atrazine removal. The appropriate ratio for atrazine removal was 3:1.

Index Terms—Activated carbon, adsorption, nano zero valence iron, atrazine.
