dye rejection by nanofiltration membrane based on polysulfone and bohemite particles modified with lysine

Polysulfone (psf) mixed matrix nanofiltration membrane was developed by blending with partially lysine alumoxane into psf. the effect of lysine alumoxane contents on membrane performance and antifouling properties were investigated. the results showed that adding modified boehmite particles to the polysulfone membrane improved the hydrophilicity and increased the permeate flux and flux recovery ratio. moreover, the filtration results of methylene blue solution showed to improve performance of the psf mixed matrix nanofiltration membranes in the dye rejection.
