英文摘要	There are traces of small-sized oil droplets and anionic polyacrylamide (APAM) in the tertiary oil recovery produced water treated with traditional technology, which causes COD value of the wastewater fail to reach the latest emission limit. In this study, Fe3O4-IDA-Cu2+ magnetic nanoparticles (MNPs) were synthesized and residual chemical oxygen demand (COD) removal in treated oil field produced water was investigated in laboratory scale. Influence of pH, dosage of magnetic nanoparticles, and stirring time was optimized for the COD removal. After 1 h of treatment, about 66.7 % COD removal was achieved with optimized parameters. Magnetic nanoparticles reusability and stability was checked by regeneration treatment. The magnetic separation showed good reusability for six consecutive runs and COD in MNPs treated wastewater was found to be below discharge limit. (C) 2021 Elsevier B.V. All rights reserved.
