Thermogravimetric analysis (TGA) was carried out to study the stability of nanoformulations used for the decontamination of mycotoxins. The TGA patterns of the nanoformulations from montmorillonite clay and Cymbopogon citratus (lemongrass) extracts were assessed with temperature ranging from ambient (20°C) to 1000°C. The various nanoformulations …

montmorillonite; acid modified montmorillonite, can be used as bleaching agent, adsorbent and so on. The modification of the inorganic salt is the ion exchange between the cation of the montmorillonite and the cation of the inorganic metal salt, so that the montmorillonite monocrystalline monolayer is formed

1 Optimization of Na-montmorillonite model . According to the basic structure properties of montmorillonite, a Na-montmorillonite crystal model with 8 unit cell (4×2×1) was established. The crystal lattice substitutions were made at the same time, and the negative charges produced by substitution were compensated by Na +.

Montmorillonite has a high specific surface area (SSA), high cation exchange capacity (CEC), and is the most common 2:1 phyllosilicate in temperate soils (Borchardt, 1989). Even in a small amount, it interferes expressively in the chemical and physical soil properties. Therefore, the proper identification of the smectite is fundamental.
