[Active aluminum oxide--a new adsorbent for concentrating intestinal viruses from water]

Concentrating properties of a new adsorbent, active aluminum oxide, towards poliomyelitis virus type III and simian rotavirus are studied using virus contamination of sewage and drinking water. Optimal concentrations of the adsorbent for effective adsorption of both rota- and polioviruses are established (1.5 and 1 g/liter, respectively) at pH typical of sewage and drinking water (7.0-8.5), as well as the optimal time of virus contact with the adsorbent (30 min). Elution conditions are determined: 3% elution agent beef extract and pH 8.5-9.5 are optimal for both viruses. Active aluminum oxide is recommended as an adsorbent for elimination of enteroviruses from water objects.
