Polymeric Membrane - an overview | ScienceDirect Topics

Polymeric membranes have been extensively used as the chemical recognition element in the design of chemical sensors. They are water immiscible phases of high viscosity and are based on the polymer matrix, which plays the role of the supporting material; and the plasticizer, which serves as the organic solvent of the membrane phase.

Ultrafiltration - Wikipedia

Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate).
