Περίληψη | Bacteriophage MS2 and ΦX174 were used as surrogates for
human viruses in order to investigate the interaction between
viruses and clay particles. The selected phyllosilicate clays
were kaolinite and bentonite (>90% montmorillonite). A series
of static and dynamic experiments were conducted at two
different temperatures (4 and 25 °C) to investigate the effect
of temperature and agitation (dynamic experiments) on virus
adsorption onto clays. Appropriate adsorption isotherms were
determined. Electrokinetic features of bacteriophages and
clays were quantified at different pH and ionic strength (IS).
Moreover, interaction energies between viruses and clays were
calculated for the experimental conditions (pH 7 and IS ) 2
mM) by applying the DLVO theory. The experimental results
shown that virus adsorption increases linearly with suspended
virus concentration. The observed distribution coefficient (Kd)
was higher for MS2 than ΦX174. The observed Kd values were
higher for the dynamic than static experiments, and increased
with temperature. The results of this study provided basic
information for the effectiveness of clays to remove viruses by
adsorption from dilute aqueous solutions. No previous study
has explored the combined effect of temperature and agitation
on virus adsorption onto clays. | en |
