Membrane
A membrane is a thin, typically planar structure or material that separates two environments. Because it sits between environments or phases and has a finite volume, it can be referred to as an interphase rather than an interface. Membranes selectively control mass transport between the phases or environments.Biological membranes include:
- plasma membrane and intracellular membranes
- mucous membrane
- Reverse osmosis
- Ultrafiltration
- Microfiltration
- Pervaporation
- Dialysis
- Electrodialysis
- Emulsion liquid membranes
- Membrane-based solvent extraction
- Membrane reactors
- Gas permeation
- supported liquid membranes
