Abstract
A method for inactivating a pathogen is described, comprising the steps of: providing, in a solution: (1) a charged polymer comprising charged monomers and counterions to the charged monomers; increasing a pH of the solution with a base, the step of increasing the pH further comprising the step of: introducing salt ions into the solution; (2) removing at least ten percent of the salt ions from the solution; (3) decreasing the pH of the solution; (4) contacting the pathogen with the charged polymer; and (5) inactivating at least fifty percent of the pathogens within thirty minutes of the step of contacting, where a conductivity of the solution is in a range of 0.1 to 10 mS/cm and/or a total cationic charge of the solution is in a range of 0.4 to 15 C/cm3.
