| Summary, etc. |
Nano-scale zero valent iron (nZVI) was synthesized in an ethanol media by reduction of ferric iron using sodium borohydride as a reducing agent under atmospheric conditions. The synthesized iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for weeks. A methodical characterization of nZVI was carried out using XRD, SEM-EDS, TEM, UV, FT-IR, XRF, TGA, and DLS studies. The acquired iron nanoparticles consist of a zero violent core embracing a rest oxide shell. The iron nanoparticles diameter was predominantly in the range of 10.0 - 100 nm. In the present study methylene blue (MB) dye and copper (II) ion removal efficiencies of laboratory synthesized nZVI particles in relation to the effect of nZVI dosages, pH, dye and Cu (II) ion initial concentrations, agitation speed, contact time and temperature, effect of salts and detergents on MB removal efficiency were determined at bench scale. In the MB case, increasing nZVI doses and temperature enhanced the decolorization of the MB by 95.81, and 91.66 %, respectively; increasing the agitation speed, contact time, and the presence of salts increased MB removal efficiency to {u2248} 100.0 %. The degradation in color decreased from 91.66 % to 72.00 % at 10.0 min with increasing concentration of dye from 10.0 mg/L to 70.0 mg/L, respectively, and to 66.87 and 36.62 % in the presence of Ariel® and Vanish® commercial detergents, respectively. In the case of copper ion, increasing nZVI doses, contact time, agitation speed, and temperature leads to improvement of Cu (II) removal efficiency up to 99.94, {u2248} 100.0, 99.83, and 99.92 %, respectively |
