The sequential extraction method separates seven Si fractions. The first four extraction steps are performed on four replicates, which are then split into two by two replicates subjected to two different treatments in the following step. ... In step 5 amorphous silica of biogenic and minerogenic origin is specified. This separation is done in ...

BET Surface Area. The surface area of the final sample was evaluated according to the BET method, the value of 146 m 2 /g (multipoint) for this horsetail-derived BAS is typical for nanostructured amorphous silica. This measurement corresponds very well with the SEM and TEM pictures, which also reveal a nanostructured biogenic amorphous silica (BAS).

myriochaetum was subject to conventional acid digestion to extract biogenic silica with a % yield remarkably higher (up to 3 times) than for other Equisetum sp. (i.e. E. Arvense). The surface area of the isolated silica was ~400 m2/g, suitable for biotechnological applications. Biogenic silicon was obtained by magnesiothermic reduction.

Abstract—Silica separation and isolation methods providing energy conservation, a decrease in losses and waste of plant raw materials, and the environmental safety of the processes are studied. Using the oxidative ashing and alkaline extraction methods, biogenic silica (SiO 2) samples with a target component content of 76.4–99.9% are prepared.

The solubility product of larch, horsetail, elm and fern phytoliths is close to that of amorphous silica and soil bamboo phytoliths. Electrophoretic measurements yield isoelectric point pH IEP = 0.9, 1.1, 2.0 and 2.2 for four grasses, elm, larch and horsetail phytoliths respectively, which is very close to that of quartz or amorphous silica ...

the amount of silica in the body decreases with age (3–5). Biogenic amorphous silica thus plays a vital role in the living environment and shows nanostructures that are very comparable with manufactured SAS. For oat husk (Avena sativa) and common horsetail (Equisetum arvense), their structures are even below 20nm.
