  • Preparation of sodium-type bentonite with useful swelling

    Preparation of sodium-type bentonite with useful swelling property by a mechanochemical reaction from a weathered bentonite. Taking advantage of the swelling of sodium type bentonite, the purification of bentonite has been done in industrial processes as well as laboratory research to obtain purified bentonites (montmorillonite containing small amount of co-existing minerals) by so-called

  • Preparation of sodium-type bentonite with useful swelling

    A weathered bentonite (Japanese acid clay), a natural resource found as a by-product in the production of bentonite, was altered by an environmentally friendly treatment, where the Japanese acid clay was mechanochemically mixed with sodium carbonate without the addition of solvent, to give sodium type bentonite. The product was subsequently purified by conventional dispersion-sedimentation

    PERMEABILITY VARIATI ON OF SODIUM ACTIVATED. sodium bentonites uniquely suited for use in barriers The focus of this study is to prepare sodium bentonite by treating the abundantlyavailable calcium bentonite with different sodium compounds and to compare the properties of activated sodium bentonite 2 MATERIALS Calcium bentonite was procured from a quarry inCoimbatore district of Tamil


    01.06.2017· The present invention relates to a method of preparing sodium bentonite. Specifically, calcium bentonite is converted into sodium bentonite by a combination of chemical, thermal and mechanical treatment procedures. The produced sodium bentonite is suitable for but not limited to oil and gas drilling and cementing applications.

  • Preparation of Adsorbent Composites Based on Bentonite

    Adsorbent composites comprising of bentonite/sodium lignosulfonate graft-polymerized with acrylamide (BLPAM) were synthesized. Results showed that the optimized preparation conditions within the experimental range were as follows: the mass ratio of acrylamide to sodium lignosulfonate was 14, the pH of the reaction medium was 4.0, the mass concentrations of the initiator and cross-linker were 0

  • Bentonite Wikipedia

    Types Sodium bentonite. Sodium bentonite expands when wet, absorbing as much as several times its dry mass in water. Because of its excellent colloidal properties, it is often used in drilling mud for oil and gas wells and boreholes for geotechnical and environmental investigations. The property of swelling also makes sodium bentonite useful as a sealant, since it provides a self-sealing, low

    Sealing a pond with bentonite is the most effective method to make the pond retain water. Sodium Bentonite clay is used for this purpose. In this article, you will learn how to seal a pond with bentonite by three methods. The methods of fix a leaking pond with bentonite are as follows-Sprinkle Method; Blanket Method; Mix Blanket Method

  • Preparation and characterization of sodium polyacrylate

    A new adsorbent, sodium polyacrylate (PAANa) grafted onto the surface of bentonite (Bent), was successfully synthesized by a facile and green Ce(IV)-redox process, for the removal of Pb 2+ from aqueous solutions.The results indicate that by this method the original layered structure of the clay can be protected along with its cation exchange capability (CEC), leading to an improved adsorption

  • Activation of Jordanian Ore Bentonite by Sodium Carbonates

    2) Preparation of sodium carbonate. 3) Activation of bentonite. The sample was divided into four portions each weighing 100g and to each portion, different percentage of Na 2CO 3 were added. The percentage ranges from 1.5% to 6%. 4) Characterization of activated bentonite.

  • Method of activation of bentonite clay

    Method of activation of bentonite clay, comprising mixing the crushed wet bentonite clay with sodium reagent activator, heating the mixture up to 40-75 o, Characterized in that the mixing bentonite clay is carried out at a moisture content of clay equal to 20-45%, and heating the obtained mixture is performed with simultaneous governanee mixture.

  • Chemical Properties of Bentonite Suspensions

    Preparation of bentonite suspensions Bentonite (montmorillonite clay of the first quality with Ca2+ and Na+ as the principal cations) was sourced from Minerali. Co. (The clay came from Vranjska banja, a spa in the southeast region of Serbia where the water temperature in the springs is 78 0C). Suspensions were made by dispersion of 1 g, 2 g and 5 g of bentonite in 100 mL of water at temperatures
