Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color which is very friable and has very low weathering resistance. It crystallizes with a monoclinic geometry. Its name is derived from the Greek glaucos (γλαυκος) meaning 'blue', referring to the common blue-green color of the mineral; its sheen (mica glimmer) and blue-green color presumably relating to the sea's surface. Its color ranges from olive green, black green to bluish green, and yellowish on exposed surfaces due to oxidation. In the Mohs scale it has hardness of 2. The relative specific gravity range is 2.4 - 2.95. It is normally found in dark green rounded brittle pellets, and with the dimension of a sand grain size. It can be confused with chlorite (also of green color) or with a clay mineral. Glauconite has the chemical formula – (K,Na)(Fe³⁺,Al,Mg)₂(Si,Al)₄O₁₀(OH)₂.

Organic modified layering silicate and preparation method thereof
InactiveCN109456621AIncrease layer spacingSimple structureNon-macromolecular adhesive additivesPigment treatment with non-polymer organic compoundsAdhesiveSolvent
The invention relates to a preparation method of organic silicate. The method comprises the following steps: pretreating the silicate by adopting a comprehensive means of heat activation, acid treatment and lithium nitrate intercalation modification to obtain lithium-based silicate, performing intercalation reaction for an organic intercalation agent and lithium-based montmorillonoid in a solventat the temperature of 80 to 180 DEG C, then purifying an organic silicate aqueous solution to obtain the organic modified silicate. The organic intercalation agent is an organic compound shown in thestructural general formula of R(CH2)12 to 18N(CH3)3R, and the R in the general formula is chlorine atoms or bromine atoms. The layered silicate is white mica subtribe and black mica subtribe and comprises sodium mica, white mica, glauconite, gold mica, black mica, iron-lithium mica and lithium mica. By adopting the method of the invention, in the preparation process, not only can the effective swelling of a space among silicate layers be realized, but also the active functional group is introduced among the layered silicate layers, the obtained organic modified layered silicate is loose, easyto break, suitable for a high-temperature polyimide adhesive / layered silicate nano composite material, and wide in application prospect.

Glauconite-based composite heavy metal wastewater treatment porous material as well as preparation method and application thereof
PendingCN113797887AGood removal effectOther chemical processesAluminium silicatesSodium BentoniteGlauconite
The invention discloses a glauconite-based composite heavy metal wastewater treatment porous material as well as a preparation method and an application thereof. The porous material is prepared from the following raw materials in parts by weight: 23-32 parts of glauconite, 15-21 parts of deacetylated chitin, 13-18 parts of sodium bentonite, 8-15 parts of a pore-forming agent, 4-10 parts of graphene oxide and 2-9 parts of sodium hydroxide. The composite powder is firstly obtained and then pressed into the pressed blank through CIP, the pressed blank is subjected to a solid-phase sintering process under the action of the pore-forming agent, and the sintering process is controlled to be finished in the sintering middle stage, so that the porous material generates a large number of pores and meets the porosity requirement while the matrix strength is guaranteed, a self-bearing structure is obtained, and the requirement for renewable utilization is met; the product is used for adsorbing and removing lead and copper in heavy metal wastewater, and has an excellent adsorption and removal effect.
