Polymeric ultrafiltration membranes modified with fly ash based carbon nanotubes for thermal stability and protein separation

The fly ash based carbon nanotubes (CNTs) were used to modify polymeric ultrafiltration membranes for protein separation. The phase inversion method was used to synthesize asymmetric polysulfone (PSF) membranes using 1-methyl-2-pyrrolidone (NMP) as solvent. Polyethylene glycol (PEG) and synthesized...
