Rectorite

Rectorite can be easily cleaved between smectite inter-layers to form 2 nm thick monolithic rectorite [101, 102]. The interlayer cations present in smectite layers in rectorite can be easily exchanged by organic or inorganic cations and hence rectorite can be used as an adsorbent for harmful metallic cations and cationic dyes [102].Rectorite - an overview | ScienceDirect TopicsRectorite is a potential hemostatic additive [119]. Nevertheless, this hemostatic additive may induce thrombus [120]. In order to avoid the formation of thrombus, it is necessary to take measures to control the release of microscopic clay mineral particles in the process of hemostasis, and this technique has some difficulties._Type Locality: ⓘ Blue Mountain Mining District, Marble Township, Garland County, Arkansas, USA. A 1:1 regular interstratification of muscovite/illite (dioctahedral mica) and montmorillonite (dioctahedral smectite). Frequently called "rectorite-K" to distinguish it from regularly interstratified paragonite/montmorillonite = "rectorite-Na".
