Membrane technology is an important part of sustainable development in water treatment processes and can provide solutions to water scarcity, water contamination, ecosystem rehabilitation, along with applications in biomedical engineering for separation processes.  Covalent Organic Frameworks (COFs) have unique structure and properties with high porosity, large surface area, and ordered pore structure.  Moreover, these properties provide opportunities for efficient organic carbon separation.  Using a neutral solute, polyethylene glycol with a molecular weight of 100,000, characterization of the membrane and its efficiency can be observed with negligible effects on rejection rate from electro-repulsion forces.  In this research, we will investigate the molecular weight cut off performance of the COF membranes with neutral particles.
