Analysis and Design of Removal of Toxic Metal Ion using Poly m-phenylene (Isophthalamide) Ultrafiltration Membranes

Poly m-phenylene (Isophthalamide) (PMIA) Ultrafiltration membranes were prepared by Non-solvent induced phase inversion technique in the presence of lithium Chloride (LiCl) with different compositions of Poly ethylene glycol (PEG-600) using N-methyl pyrrolidone (NMP) solvent. The effects of compositions of PEG-600, pure water flux and percentage water content of the membranes were studied. The application of PMIA membranes in separation of toxic heavy metal ions from solutions was also attempted and the results were discussed.
