| titleOfInvention | Manufacturing method of reverse osmosis membrane with high flux and high exclusion ratio of salts |
| abstract | The present invention relates to a method for producing a reverse osmosis composite membrane having a high flow rate and a high salt rejection, and in particular, reacts an organic solution containing polyamine and polyacyl halide, polysulfonyl halide or polyisocyanate in an aqueous solution layer impregnated with a porous support. It is an object to make a reverse osmosis composite membrane having an improved flow rate and salt rejection rate by the reaction product produced by the.n n n Method for producing a reverse osmosis composite membrane according to the present invention comprises the steps of removing the excess solution by probe the porous support in a polyamine aqueous solution; Coating the reaction product on the surface of the porous support by reacting the aqueous polyamine solution contained in the porous support with an organic solution containing polyacyl halide, polysulfonyl halide or polyisocyanate, wherein the polyacyl The halide is selected from trimethoyl chloride, isophthaloyl chloride, terephthaloyl chloride or a mixture thereof using a hydrocarbon, and the organic solution is selected from the group comprising carbon tetrachloride, chloroform, dichloromethane or mixtures thereof. It is characterized in that one additive is added. |
