This article presents the microwave-assisted extraction of biosilica from common reed (Phragmites australis) biomass and the utilization of the resulting aqueous extract to enrich porous ceramic granules based on diatomaceous earth and bentonite from white wine cleaning. The enriched porous ceramic granule generated a solution of soluble silicon that was +23.4 ± 2.2 more concentrated than the porous ceramic granules not enriched with reed extract. The water reactivity of Si-O-Si groups is higher in the polysilicic acid formed via the polycondensation of silicic acid extracted from reed, compared to the Si-O-Si group from diatomaceous earth or bentonite.
