Abstract

Provided is a method for modifying a reverse osmosis membrane for the purpose of improving the quality of water permeated through the reverse osmosis membrane, while suppressing deterioration of the reverse osmosis membrane. A method for modifying a reverse osmosis membrane, wherein: a bromine-based oxidant or a reaction product of a bromine compound and a chlorine-based oxidant and a sulfamic acid compound are brought into contact with a polyamide-based reverse osmosis membrane; or alternatively, a reaction product of a sulfamic acid compound and a bromine-based oxidant or a reaction product of a bromine compound and a chlorine-based oxidant is brought into contact with a polyamide-based reverse osmosis membrane.
