Surface modification of natural clay with H2O2 for high adsorption of acid Red 114: Experimental and modelling studies

Cetyltrimethylammonium Bromide-Modified Laponite@Diatomite Composites for Enhanced Adsorption Performance of Organic Pollutants

“…Natural clay is commonly used for the adsorption of cationic dyes due to its surface electronegativity and hydrophilicity . However, limited by its purification process, the adsorption capacity of natural clay is usually low, and it is difficult to adsorb anionic organic pollutants. , Laponite, a synthetic clay composed of layered nanosheets mainly composed of lithium magnesium silicate, has been proven to have good cationic pollutant adsorption properties . For example, the design of Laponite hydrogels has shown high adsorption capacity for methylene blue. , However, the aggregation of adjacent nanosheets can lead to incomplete release of adsorption sites, thereby reducing its adsorption performance .…”

Cerium-Doped TiO2 and Sepiolite Nanocomposites for Tetracycline Inactivation in Water Treatment

“…Among the adsorbent materials studied, nanoclay minerals stand out, such as montmorillonite, palygorskite, Sepiolite, and zeolites. − These materials are abundant, possess good stability, are nontoxic, have a high surface area, and exhibit a high adsorption capacity. , Between the family of the nanoclay minerals, Sepiolite (Sep) is a hydrated magnesium silicate clay mineral with a chemical formula of Si 12 Mg 8 O 30 (OH) 4 (OH 2 ) 4• 8H 2 O, which describes a needle-like morphology. The physicochemical properties of Sepiolite indicate that it is an excellent material in the fields of adsorption and catalysis and has excellent environmental applications …”
