Silicates as Nonspecific Adsorbents of Bacteriophage: a Model for Purification of Water from Viruses


Amorphous silicates having small particles with a large surface area were found to have high nonspecific adsorption capacity. Investigations with Escherichia coli T4 bacteriophage have shown adsorption capacity of up to 99.9% on different tested silicates. Optimal conditions for the adsorption of T4 bacteriophage on various commercially available silicates were determined. A continuous-flow adsorption of T4 bacteriophage on silicates appears to be a model system for the removal of viruses from potable water and sewage.
