Separation of macromolecular proteins and rejection of toxic heavy metal ions by PEI/cSMM blend UF membranes

- First time we are using PEI/cSMM blend UF membranes for macromolecular protein and toxic metal ion removal.
- cSMM is blended with PEI to improve separation performance, MWCO, pore size and porosity.
- Modified UF membranes possessed higher protein and metal ion permeate flux.
- Rejection performance of toxic metal ions found to be great in higher PETIM ligand concentration.
- Stability complexation of PETIM with metal ion also plays significant role in metal ion rejection.
