Surface-water purification using cellulose paper impregnated with silver nanoparticles

Microwave-assisted incorporation of silver nanoparticles in paper for point-of-use water purification.

This work reports an environmentally benign method for the in situ preparation of silver nanoparticles (AgNPs) in paper using microwave irradiation. Through thermal evaporation, microwave heating with an excess of glucose relative to the silver ion precursor yields nanoparticles on the surface of cellulose fibers within three minutes. Paper sheets were characterized by electron microscopy, UV-V...

Plasma treated activated carbon impregnated with silver nanoparticles for improved antibacterial effect in water disinfection

A strategy to selectively attach more Ag nanoparticles on the external surface of activated carbon (AC) is being proposed and used as an antibacterial medium for water disinfection. Ag nanoparticles were first synthesized under UV irradiation by reducing silver nitrate with sodium citrate; the latter serving the dual purpose of both a reducing and a capping agent. Transmission electron microgra...

Antimicrobial effect of silver-impregnated cellulose: potential for antimicrobial therapy

BACKGROUND Silver has long been known to have antimicrobial activity. To incorporate this property into multiple applications, a silver-impregnated cellulose (SIC) with low cytotoxicity to human cells was developed. SIC differs from other silver treatment methods in that the leaching of silver particles is non-existent and the release of ionic silver is highly controlled. RESULTS Candida albi...
