The present disclosure relates to a preparation method of a super absorbent polymer containing a novel cross-linking agent compound. The preparation method of a super absorbent polymer of the present disclosure can provide a super absorbent polymer exhibiting excellent absorption properties and an excellent deodorizing effect by including a cross-linking agent with a novel structure. Therefore, according to the present disclosure, since a separate additive for a deodorizing property is not required, processability and economic efficiency of the manufacturing process can be improved.
