Mitigation of Silver Ion Loss from Solution by Polymer Coating of Metal Surfaces, Part II 

Vance, John; Delzeit, Lance (2020 International Conference on Environmental Systems, 2020-07-31)
“Spacecraft potable water systems require a biocidal agent that effectively provides both immediate and residual disinfection over long periods of time. Ionic silver (Ag+) is a leading candidate for this application, but ...
