摘要
Disclosed are an amine aqueous solution for forming an active layer of a polyamide reverse osmosis composite membrane and a preparation method of the polyamide reverse osmosis composite membrane using the same. The amine aqueous solution comprises 0.1 to 20 wt % of a polyfunctional amine compound, 0.1 to 20 wt % of an alcohol amine compound, 0.1 to 20 wt % of a tertiary amine compound, and 40 to 99.7 wt % of water. Due to using an amine aqueous solution having an alcohol amine and a tertiary amine compound, the polyamide reverse osmosis composite membrane has high water permeability and enhanced salt rejection rate, and thus is useful for the membrane field.
