The goal of the study was to evaluate the efficiency of iron nanoparticles (GT-NZVI), synthesized by a green synthesis route, for Cr(VI) removal in a pilot-scale application. A tank with dimensions of 2.5 m (width) x 3.75 m (length) x 1.5 m (height) was constructed and filled with 24 tons of soil. First, 3 m3 of GT-NZVI suspension was injected and then the supply of contaminated water containing 5 mg/L Cr(VI) was initiated. Samples were analyzed for pH, redox potential, and electric conductivity as well as Fetot and Cr(VI). The reactive zone operated efficiently for the treatment of contaminated water for 1 year.
