The supports materials were Celite 545, Sephadex G-25, and chitosan.
Mined and processed from the world's purest deposits of diatomaceous silica, Celite is available in nine standard grades for efficient filtering of all liquids.
The reaction mass was filtered on celite pad and washed with MeOH.
Physical entrapment has been employed in many commercial carriers, for example, controlled pore silica, natural/synthetic polymers, hollow fiber, activated charcoal, aluminum oxide, and celite [4, 74-76].
The mixture was cooled down to room temperature and filtered over Celite. The filtrate was evaporated, and the crude product was dissolved in CH[Cl.sub.3].
The aqueous phase was boiled with charcoal (50 mg), filtered through Celite and then concentrated in vacuo to give [DE.sub.2], as white solid: m.p.

In Milan and Genoa, we used passive samplers (stainless-steel tube, 9-mm internal diameter, 90-mm length) containing Chromosorb 106 [R] (Celite Corp., Lompoc, CA, USA) and equipped with a diffusion chamber (Brown 1999).
