اقرأ أكثرThe mineral assemblage of the rectorite pelite is rectorite, halloysite, illite, gypsum, pyrite and rutile, suggesting a weak supergene alteration. Several features related to crystallization of halloysite were noted. Growth of halloysite on rectorite edge surfaces in voids and twins of halloysite on a nanometer scale with composition plane ...
اقرأ أكثرRectorite is a regularly interstratified clay mineral with alternate pairs of dioctahedral mica-like layer (nonexpansible) and dioctahedral montmorillonite-like layer (expansible) in 1:1 ratio. ...
اقرأ أكثرFor rectorite powders (0:1), although montmorillonite-like layers were expansive, there were a lot of hydrated cations (e.g., Na +, Ca 2+, and Mg 2+) that easily dissociated in water between layers [46], which could be exchanged with cations and be used to adsorb cationic dyes. However, the powdered rectorites quickly settled to the bottom ...
اقرأ أكثرNowadays, most of mineral-based adsorbents are powder form, which makes them inconvenient to collect and always easy to cause secondary pollution. In this work, an organic rectorite composite nanofiber membrane (SRt-PAN) was designed and prepared by electrospinning technique. The as-received composite nanofiber membranes were …
