Abstract	Background and Purpose: Organic dyes with a complex structure are often tox ic, carcinogenic, mutagenic, non-biodegradation and stable in the env ironment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscale zero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materials and Methods: This study was conducted at the laboratory scale. I n this study, the removal efficiency of AR18 from a synthetic solutio n by NZVI was investigated. As well as the effect of solution pH, dye concentration, the conce ntration of NZVI and contact time in decolorization efficiency was investigated . Results: The results show that in pH = 3, contact time of 80 minutes, dye concentration of 25 mg/l and concentration of NZVI of 2 g/l, the removal eff iciency was about 94%. Conclusion: According to the results of experiments, NZVI has high efficiency in removal of AR18 from aqueous solution.
