Abstract
The present invention relates to a method including reacting a solution of a salt of a biocidal metal with an active layer of water purification membrane, discarding the biocidal metal salt solution such that a thin layer of the biocidal metal salt solution remains on the membrane surface, reacting a reducing agent solution with the active layer of the membrane and the thin layer of the biocidal metal salt solution thereby forming a biocidal metal nanoparticle-modified membrane, removing the reducing agent solution, and rinsing the biocidal metal nanoparticle-modified membrane.
