| titleOfInvention | A kind of polyamide ceramic composite nanofiltration membrane containing MoS2 intermediate layer and preparation method thereof |
| abstract | A polyamide ceramic composite nanofiltration membrane containing a MoS 2 intermediate layer and a preparation method thereof belong to the technical field of membrane separation. The method includes the following steps: weighing the molybdenum source and the sulfur source compound, adding deionized water to obtain a precursor solution, pouring the precursor solution into the para-polyphenylene lining, and completely immersing the tubular ceramic matrix in the precursor solution; Then, the lining is sealed and placed in a stainless steel reaction kettle, and the reaction is carried out at a constant temperature of 100-360 ° C to obtain a ceramic matrix containing a MoS 2 intermediate layer; the ceramic matrix containing the MoS 2 intermediate layer is immersed in the aqueous monomer solution, Take it out, immerse it in an organic solution of oil phase monomer after drying, and perform interfacial polymerization; finally, heat the composite membrane at 30-100°C. The invention is beneficial to promote the formation of a continuous and uniform polyamide separation layer during the interfacial polymerization process, and significantly improves the separation performance of the composite membrane. |
