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