Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red ۱۸ (AR۱۸) from aqueous solutions. Materials and Methods:This study was conducted at the laboratory scale. In this study, the removal efficiency of AR۱۸ from a synthetic solution by NZVI was investigated. As well as the effect of solution pH, dye concentration, the concentration of NZVI and contact time in decolorization efficiency was investigated. Results:The results show that in pH = ۳, contact time of ۸۰ minutes, dye concentration of ۲۵ mg/l and concentration of NZVI of ۲ g/l, the removal efficiency was about ۹۴%. Conclusion:According to the results of experiments, NZVI has high efficiency in removal of AR۱۸ from aqueous solution.
