Abstract

PURPOSE: To offer the membrane useful over a long period of time, of which the outflow rate is increased and the factor of change of outflow speed of water (m value) is brought close to zero, by crosslinking the membrane for reverse osmosis produced from the specified polymer having the substantially linear aromatic organic nitrogen bond with the transition metals, metals of Al group or metals of lead group.
