Article Synopsis
- - Natural glauconite was exfoliated to create methoxy exfoliated glauconite (Mth/EXG), which was tested for its ability to adsorb water contaminants like phosphate, safranin-O dye, and cadmium ions.
- - Mth/EXG demonstrated impressive adsorption capacities: 269.9 mg/g for phosphate, 312 mg/g for safranin-O, and 234.5 mg/g for cadmium, outperforming more expensive adsorbents.
- - The adsorption processes were governed by physical mechanisms such as hydrogen bonding and van der Waals forces, and the reactions were spontaneous and exothermic, indicating strong interactions with the pollutants even in complex chemical environments.
Two forms of morphologically transformed glauconite (GL) involved exfoliated nanosheets (EXG) and nanorods (GRs), which were synthesized by facile exfoliating and scrolling modification under sonication. The two advanced forms (EXG and GRs) were applied as enhanced adsorbents for U(vi) ions and compared with using raw glauconite. The developed GRs structure displays higher saturation retention properties (319.

The synthetic nanostructure was characterized by different analytical techniques as a superior adsorbent for the malachite green dye (MG). The synthetic GNRs were detected as porous nanorods with an average length of 150 nm to 5 μm, an average diameter of 25 to 200 nm, and a specific surface area of 123.
