Bacteriophage inactivation as a function of ferrous iron oxidation

Abstract

Iron-based disinfection has been promoted as a potential low-cost, low-byproduct means of virus mitigation.

Electrocoagulation as a Pretreatment for Electroxidation of E. coli

“…Beyond physical removal, as the pH drops, E. coli inactivation may play an increasingly important role during EC. For example, the oxidation rate of ferrous to ferric iron is slower at lower pH (Equation (3) [50]), resulting in a greater prevalence of reactive iron species [12,51]. Thus, lower pH leads to higher ferrous iron concentrations, which are capable of inactivating E. coli and viruses due to ferrous iron oxidation [8,28,51,52].…”

Disinfection and antimicrobial processes

“…McDermid, McDermid, & Mayer, 2019). Besides, it was found that slower oxidation promoted inactivation as the decreases in pH and dissolved oxygen both led to greater inactivation (Heffron, McDermid, et al, 2019).…”

Chu, Ryberg, Loeb, Suh, and Kim (2019) reviewed the recent developments in the area of utilizing sunlight to disinfect water in a point-of-use (POU) disinfection system for producing tangible health benefits in the most susceptible rural communities.…”

“…Moreover, employing EC‐EO hybrid process was found to be of benefit only in treating the synthetic surface water matrices, while in the case of synthetic groundwater matrices, using EC alone was as nearly similar or better than the EC‐EO hybrid process (Heffron, Ryan, et al, 2019). In another research, it was found that the activation of MS2 and P22 bacteriophages at circumneutral pH depended on both the extent and the rate of iron oxidation (Heffron, McDermid, McDermid, & Mayer, 2019). Besides, it was found that slower oxidation promoted inactivation as the decreases in pH and dissolved oxygen both led to greater inactivation (Heffron, McDermid, et al, 2019).…”
