Dialysis

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Area of Science:

Materials Science
Chemical Engineering
Environmental Science

Background:

Used engine oil (UEO) presents environmental challenges due to contaminants.
Effective separation technologies are needed for UEO treatment and resource recovery.

Purpose of the Study:

To investigate the performance of poly(acrylonitrile-co-methyl acrylate) (P(AN-co-MA)) ultrafiltration (UF) membranes for UEO separation.
To evaluate membrane fouling and cleaning efficiency.

Main Methods:

Fabrication of a UF membrane (23 nm pore size) using P(AN-co-MA) via non-solvent-induced phase separation.
Filtration of diluted UEO using a dead-end filtration setup.
Characterization of the membrane using FTIR, 13C NMR, and XRD.
Analysis of membrane fouling and flux recovery after toluene washing.

Main Results:

Initial UEO solution permeability dropped significantly but stabilized, indicating fouling.
Washing with toluene recovered 79% of the initial flux, showing good resistance to irreversible fouling.
The P(AN-co-MA) UF membrane achieved 96.3% rejection of polymerization products and metals from UEO.

Conclusions:

P(AN-co-MA) UF membranes are suitable for separating contaminants from used engine oil.
The membranes exhibit promising fouling resistance and effective removal of key pollutants.
This technology offers a viable approach for UEO treatment and potential oil reclamation.
