The variables of initial concentration, time, pH, adsorbent dose was examined. The characterization of NZVI/AC was carried out by SEM-EDS and XRD analysis. The adsorption isotherms and kinetics of humic substances on AC and NZVI/AC were studied. The findings showed that the particle size of synthesis NZVI were in the range 20-50nm. The experimental data followed the Langmuir isotherm and pseudo-second kinetic model. For AC, optimum conditions of initial concentration, pH, contact time, and adsorbent dose were 5 mg L-1, 4.43, 46.28 min, and 1.5 g L-1, respectively. For NZVI/AC, optimum conditions of initial concentration, pH, contact time, and adsorbent dose were 5.48 mg L-1, 5.44, 44.7 min, 0.65 g L-1, respectively. Predicted removal efficiency by Box-Benken models for activated carbon and NZVI were 60 and 100 percent, respectively. </p></abstract><publication_date><month>12</month><day>11</day><year>2017</year></publication_date><pages><first_page>57</first_page><last_page>68</last_page></pages><publisher_item><identifier id_type="pii">gnest_02264</identifier></publisher_item><doi_data><doi>10.30955/gnj.002264</doi><timestamp>1714050992</timestamp><resource>https://journal.gnest.org/publication/gnest_02264</resource></doi_data></journal_article></journal></body></doi_batch> </div>
