Abstract
The present disclosure belongs to the technical field of membrane separation, and discloses a preparation method of a Ti3C2Tx MXene quantum dot (MQD)-modified polyamide (PA) reverse osmosis (RO) membrane. The preparation method includes the following steps: subjecting a Ti3C2Tx MXene material to liquid nitrogen intercalation and interlayer expansion to obtain a Ti3C2Tx MQD nanomaterial; preparing an aqueous phase solution with the Ti3C2Tx MQD nanomaterial and an organic phase solution; soaking an ultrafiltration (UF) base membrane in the aqueous phase solution , and removing the aqueous phase solution on a surface of the UF base membrane through blow-drying; soaking the second UF base membrane in the organic phase solution to allow interfacial polymerization to form an active layer; and allowing a composite membrane obtained after the interfacial polymerization to stand, followed by a heat treatment to further promote the interfacial polymerization.
