A continuous flow-through (FT), hydrothermal synthesis technique to produce polyvinyl-pyrrolidone-coated iron oxide nanoparticles (NP) under ambient conditions that converted the previously used facile one-pot batch process was developed. NP can be used for oil remediation in environmental systems, but a scaled-up synthesis is required for practical applications. The synthesis technique requires low temperatures and ambient pressure and does not use any inert gases and organic solvents. The method has potential to be developed into a massively parallel process for large-scale production. Analysis showed that NP produced from FT synthesis largely maintained their structural properties, although both core and hydrodynamic size of the NP were slightly larger than those from the batch method, potentially affecting specific surface area and their ability to remove oil from aqueous solutions under challenging conditions. Results showed that NP synthesized from the FT technique showed excellent oil removal capacity.
