摘要: To provide a reverse osmosis membrane where both salt rejection rate and water permeability required for wastewater treatment are achieved in a high level in spite of using the materials having excellent resistance to chemicals (resistance to alkali and to chlorine).A reverse osmosis membrane for wastewater treatment comprising a sulfonated poly(arylene ether sulfone) polymer containing a constituting component represented by the following formula [I], characterized in that, in a proton nuclear magnetic resonance spectrum where water molecules in the membrane are measured using the reverse osmosis membrane in a water-containing state, the relation between the chemical shift A (ppm) of spectral peak top derived from bound water and the chemical shift B (ppm) of spectral peak top derived from bulk water satisfies (B−0.36)≦A
