Scalable synthesis and purification of functionalized graphene nanosheets for water remediation

Microwave (MW) accelerated synthesis combined with microfiltration (MF) on commercial hollow fiber modules enables fast and scalable preparation of highly pure modified graphene oxide nanosheets. The MW-MF procedure is demonstrated on polyethylenimine (PEI) modified GO, and the so-obtained GOPEI is used for simultaneous removal of arsenic and lead from water.

Automated summary

The study demonstrates that microwave accelerated synthesis combined with microfiltration enables fast and scalable preparation of highly pure modified graphene oxide nanosheets, which could be used for simultaneous removal of arsenic and lead from water.
