Water treatment membrane production method, water treatment membrane produced using same, and water treatment module comprising water treatment membrane

A method for manufacturing a water-treatment membrane comprising:

• preparing a porous support;
• and
• forming a polyamide active layer on the porous support using interfacial polymerization of an aqueous solution including an amine compound and an organic solution including an acyl halide compound,
• wherein:
• the organic solution further includes a compound of Chemical Formula 1:
• wherein:
• R is hydrogen, deuterium, a nitrile group, a halogen group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
• X and Y are the same as or different from each other, and each independently is a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
• and
• n is an integer of 1 to 10, and when n is 2 or greater, structures in the parentheses are the same as or different from each other;
• and
• an amount of Chemical Formula 1 present in the organic solution is greater than or equal to 0.0001 parts by weight and less than or equal to 10 parts by weight with respect to 100 parts by weight of the organic solution.
