(115g) Application of Batch Technique to Study Adsorption of MS2 Bacteriophage to Natural Organic Matter (NOM)

The research used Batch Technique to study the adsorption of MS2 bacteriophage to silica bead coated with Suwanee River Natural Organic Matter (SRNOM) in the presence of Ca2+ and Mg2+. The objective of this research is to understand the role of divalent cations on adsorption mechanism of MS2 to natural organic matter. Adsorption of MS2 to SRNOM-coated silica bead carboxylic group of MS2 and SRNOM increases significantly in the presence of Ca2+. It is hypothesis that the effect is due to cation bridging formed between the carboxylic group of MS2 and the carboxylic group of SRNOM. In the other hand Mg2+ reflects a lower adsorption rate because has a low interaction with NOM due to its strongly held hydration shell, neutralizing the charge of NOM. This research will help us understanding the transport of MS2 virus in natural water and whether it can be retained by natural processes.
