Virioplankton 'pegylation': use of PEG (polyethylene glycol) to concentrate and purify viruses in pelagic ecosystems Pharmaceuticals and Care Products in the Environment Scientific and Regulatory Issues Ultrafiltration: an efficient second step for hepatitis A virus and poliovirus concentration Virus Adsorption to Microporous Filters Modified by in situ Precipitation of Metallic Salts Concentration of viruses from water by using cellulose filters modified by in situ precipitation of ferric and aluminum hydroxides EPA Method 1615. Superior performances of virus concentration were achieved with much less addition of trivalent aluminum salts (AlCl 3 and Al 2 (SO 4 ) 3 ) when controlling the pH to below 5 (Wallis et al., 1972) .	cache/cord-296661-6ndn2qxc.txt	txt/cord-296661-6ndn2qxc.txt
