| 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 |
