Synthetic magnesium silicates are white, odorless, finely divided powders formed by the precipitation reaction of water-soluble sodium silicate (water glass) and a water-soluble magnesium salt such as magnesium chloride, magnesium nitrate or magnesium sulfate. The composition of the precipitate … Skatīt vairāk Unlike natural magnesium silicates like talc and forsterite olivine which are crystalline, synthetic magnesium silicates are amorphous. Synthetic magnesium silicates are insoluble in water or alcohol. The particles are … Skatīt vairāk • Talc, a natural magnesium silicate • Diatomaceous earth, a natural silicon-based filter material Skatīt vairāk The very large active surface makes synthetic magnesium silicate useful for a wide variety of applications: purifying adsorbent (polyols, animal and vegetable oils, chromatography, dry cleaning, sugar, resins, odors); filler (rubber, ceramics, paper, glass, … Skatīt vairāk TīmeklisChromatography on Florisil® (activated magnesium silicate) was used to separate model compounds representative of hydrocarbons, cholesterol esters, triglycerides, free sterols, diglycerides, monoglycerides, and free fatty acids. The order of elution was the same as that observed in silicic-acid chromatography except that free fatty acids …

Tīmeklis(GCB), aminopropyl and Florisil SPE columns for the clean-up step and followed by gas chromatogra-phy for the determination of certain organochlorine and organophosphorus pesticide residues. Both polar and nonpolar pesticides could be effi ciently recovered from eggs with a range between 86–108% and 61– 149%. TīmeklisFlorisil is magnesium silicate that removes interfering substances that are not removed by other sorbents. The typical activation is carried out overnight at 130 °C and cooled in a desiccator, but it may be further heated to increase adsorption capacity or weakened by addition of water. Florisil PR (60/100 mesh) is suitable for a pesticide cleanup … いいものめぐり
