Virus inactivation is commonly described by a first order inactivation

2. Material and methods
2.1. Inactivation experiments
Prevailing conditions for each experiment are given in Table 1. In experiments A – E, Ubenimex ranged from pH 4 – pH 8 at a constant sodium concentration of 1 mM. In experiments F – Q, the combined effects of pH (pH 5 – pH 8) and sodium concentration (1, 10 and 20 mM) on inactivation were investigated. In experiments R – T, the effect of calcium concentration (1, 1.5 and 3 mM) at the same IS was studied. Experiments A – E were conducted at 12 ± 05 °C and experiments F – T at image 9.5 ± 0.5 °C. Note that these ranges of conditions (temperature, pH, sodium and calcium concentration) are representative for Dutch groundwater shallow aquifers (Sadeghi et al., 2011).
