Abstract |
Model enteric viruses were concentrated from seeded samples of raw, finished and granular activated carbon (GAC)-treated waters and from GAC-treated waters supplemented with humic or fulvic acid or bentonite clay particles by adsorption to electropositive (Virosorb 1MDS) filters at pH 7.5 or electronegative (Filterite) filters at pH 3.5 with and without 5 mM added MgCl2, followed by elution with 0.3% beef extract in 50 mM glycine at pH 9.5. Soluble organic compounds reduced virus adsorption efficiencies from both raw and finished waters compared to GAC-treated water. Humic and fulvic acids caused reductions in poliovirus adsorption and recovery efficiencies with both types of filters. The results suggest that high concentrations of soluble organic matter and suspended solids may interfere somewhat with virus recovery by filter adsorption-elution methods. |
