Abstract

World Health Organisation (WHO) reports that one sixth of the world's population does not have the access to safe water. The recent advancement of science paves many routes to provide secured water, in which nanotechnology plays a very vital role by providing many low cost ways of purification and disinfection of drinking water. The aim of the present work is to design silver embedded nanoceramic porous water purifier using clay, rice husk, and silver nitrate at a low cost measure. The synthesised nanoparticles in the present experiment was characterised and confirmed by UV-Visible spectrometry, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and x-ray powder diffraction (XRD). From the analysis it was found that the leaching of silver from the ceramic porous disc was below the values of WHO standards. The antimicrobial activity of the disc was assessed against E. coli and found to be very effective.
