Abstract:
An object is to realize a novel reverse osmosis membrane (more specifically, reverse osmosis composite membrane) that is capable of suppressing biofouling. The object is attained with use of a reverse osmosis composite membrane which is obtained by chemically modifying a surface thereof with a compound that has an amino group and that is obtained by modifying the amino group with two molecules of α-picolyl group and has a dipicolylamine structure.
