摘要

Cr(VI) was reduced from synthetic, real drinking waters and real electroplating wastewater using the Fe3O4-WO3-3-aminopropyltriethoxysilane nanoparticles, as a heterogeneous catalyst, in the presence of visible light. The nanocatalyst was prepared via a simple co-precipitation method. FT-IR and SEM techniques proved the effective presence of an amino group. Under the optimum conditions: pH = 2, [Cr(VI)](o) = 10 mg/L , citric Acid = 10 mg/L, and nanocatalyst dosage = 6 g/L, 99.96% of Cr(VI) was removed after 300 min. Approximately 82.96% of Cr(VI) in a real water sample was removed after 1440 min under the optimal circumstances. Also, full treatment of electroplating wastewater was reached after 2880 min.
