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.
Claims5
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 represented by the following formula (1),
- the compound that has the amino group being the compound in a monomeric form,
- (in the formula (1), each R is independently selected from the group consisting of a hydrogen atom, halogen atoms, a nitro group, a cyano group, an amino group, alkyl groups having 1 to 6 carbon atoms, and alkoxy groups having 1 to 6 carbon atoms and may be identical or different, and the dipicolylamine structure may form a complex with a metal M).
