Experimental conditions for inactivating adenovirus type 2 virions with monochloraminea
| Expt | N0 (PFU/ml) | c0 (mg/liter as Cl2) | x (dimensionless) | tf (min) |
|---|---|---|---|---|
| MN-M-1 | 4.39 × 106 | 7.07 | 3.50 | 44.2 |
| MN-M-2 | 5.23 × 106 | 7.46 | 3.53 | 42.2 |
| MN-M-3 | 3.92 × 106 | 5.82 | 4.43 | 51.2 |
a
Experiments MN-M-1, MN-M-2, and MN-M-3 were performed to assess the molecular mechanism of monochloramine. N0, initial virus titer; c0, initial disinfectant concentration; x, ammonia nitrogen-to-chlorine (NH3-N/Cl2) molar ratio; tf, maximum time for which viruses were exposed to monochloramine. Other conditions equal for all experiments: pH 8.0 ± 0.2; PBS concentration, 0.01 M; temperature, 20 ± 1°C.
