Therefore, facile and novel method for surface immobilization of silver nanoparticles needs to be developed.
These nanoparticles were uniformly distributed on the surface of nanofibers with no apparent agglomeration at a silver loading up to 4.36 wt.% (c PAN-Ag1.5).
The silver-incorporated membrane c PAN-Ag1.5 achieved a high pure water flux of 130 Lm at 10-cm water head, demonstrating the feasibility of energy-efficient gravity-driven filtration and eliminating the need for electrical power. The strategy reported here provides an efficient and green route to synthesize point-of-use membranes.
Providing safe drinking water in disaster-affected areas plays a critical role to prevent the outbreak of waterborne diseases in the aftermath.
Conventional surface water treatment typically involves coagulation, filtration, and/or chemical disinfection.
