摘要：
Provided is a composition for interfacial polymerizing polyamide including an amine compound; and one or more types of compounds selected from among a purine-based compound and a pyrimidine-based compound of Chemical Formula 1:
wherein, in Chemical Formula 1:
X is N or NH;
Y is O or OH;
Z is O, OH or NH2;
R1 and R2 are each hydrogen or a substituted or unsubstituted alkyl group; and
is a single bond or a double bond,
and a method for manufacturing a water-treatment membrane and a water-treatment membrane using the same.
