Types of Bentonite: Two types of bentonite are recognized, and the uses of each depend on specific physical properties. Type 1 Sodium Bentonite. Sodium Bentonite is the type of swelling clay. It has single water layer particles which contain Na + as the exchangeable ion Type 2 Calcium Bentonite. Calcium Bentonite is the non-swelling clay.

As seen in Fig. 4, the equilibrium adsorption capacity decreased from 2.745 × 10 −4 to 0.291 × 10 −4 mol/g when the pH increased from 2 to 12. The high adsorption capacity may be attributed to both the strong electrostatic interaction between –N + (CH 3) 3 of CTAB-bentonite and anionic dye molecules (as –SO 3 − anion), and the replacement …

Components & How It Works. The main component is montmorillonite, a soft clay formed by layers of silica and alumina. Montmorillonite is normally bound to many clay minerals, especially sodium, calcium, magnesium, and aluminum [8, 3]. Bentonite may also contain small amounts of impurities such as other clays (illite, kaolinite) and crystalline …

What you do is add linseed oil from a burette to 100g of pigment and mix with a spatula until a smooth paste is formed. The number of grams (or millilitres) of oil absorbed is then called the Oil Absorption. One lab technician may mix the paste until it went shiny; another technician may decide on a different end point.
