    摘要： A reverse osmosis membrane that has alkali resistance, and therefore can maintain high boron rejection performance even at high pH region, and a method for producing the membrane are disclosed. The reverse osmosis membrane has an initial performance that a rate of change Rf (%) determined by the following equation is within ±10%: Rf(%)=((F1-F0)/F0)×100 wherein F0 is a permeation flux (m3/(m2/day)) at the initiation of operation when a sodium hydroxide aqueous solution adjusted to pH 12.0 as raw water is continuously circulated at 25° C. under pressure of 0.75 MPa, and F1 is permeation flux (m3/(m2/day)) after one week operation.
