Equilibrium deposition filtration EDF

An alternative method used for preparing supported catalysts is the Equilibrium Deposition Filtration (EDF) technique, otherwise called equilibrium adsorption. Following this technique the support is immersed in a large volume of a dilute aqueous solution of the TMIS, ideally at fixed pH and ionic strength. Equilibration of the suspension follows for several hours under stirring. During equilibration the TMIS are deposited at the interface developed between the support surface and the aqueous solution. We call this mode of deposition interfacial deposition. In the filtration step the interfacially deposited TMIS are practically separated from the non-deposited ones.
