Incorporation of layered double hydroxide nanofillers in polyamide nanofiltration membrane for high performance of salts rejections

In this work, thin film composite (TFC) membrane embedded with self-synthesized layered double hydroxide (LDH) nanofillers was prepared via interfacial polymerization technique for nanofiltration (NF) process. Prior to filtration experiments, the morphologies and physicochemical properties of the pr...
