Abstract:

The objective of this research is to elucidate the main disinfectant mechanism of nanosilver and to evaluate its interaction with the biological, chemical and physical components of natural waters. Silver nanoparticles interact differently with different dissolved and particulate compounds commonly present in drinking water depending upon the disinfectant mechanism.

Our preliminary results show that concentrations of silver nanoparticles below 5 mg/L can achieve removal percentages higher than 99%. Additional results will be presented for silver nanoparticles disinfectant kinetics, and the effects of dissolved inorganic and organic matter in water on the disinfection process
