New approaches to virus removal: the way to produce virus-free drinking water.
Virus control in drinking water is considered one of the serious problems to be encountered in the near future. Trials to remove viruses from drinking water were directed to enhance water treatment processes, use of different disinfectants or use of a good virus adsorbent material. In the present study, four materials were prepared, dimethylaniinoethyl chitin, chitosan and cellulose and starch acrylate and examined for adsorption of hepatitis A virus from drinking water. Also, three types of eluates (3% beef extract-glycine, 3% beef Virus control in drinking water is considered one of the serious problems to be encountered in the near future.

Also, three types of eluates (3% beef extract-glycine, 3% beef extract and glycine) were used for virus recovery from adsorbed materials. The results obtained showed that dimethylaminoethyl chitosan was a good adsorbent (99.16%) and the three eluents were poorly desorb viruses.
