A layered composite of Fe 2 O 3-pillared bentonite (Fe-P-Bet), used as a catalyst in a Fenton-like process, was prepared and then its mechanical activation was studied in detail.The optimum conditions for preparation of Fe-P-Bet and the effects of mechanical activation on the catalytic activity of Fe-P-Bet were investigated systematically.

For successful adsorption, enzyme to bentonite ratios greater than 0.4 (w/w) have to be used as lower ratios lead to 90% enzyme inactivation due to bentonite contact. In addition, covalent linkage using the activated oxiran carriers Eupergit C and Eupergit C250L as well as linkage with aminopropyl silica via metaperiodate activation of glycosyl ...

Bentonites are rocks mostly consisting of swelling clay minerals. They were first described from the Cretaceous Benton Shale near Rock River, Wyoming, USA. Because of their useful properties (e.g. highly adsorbent, cation exchanging, swelling), bentonites have many uses, in industry (among them as drilling mud, purification agent, binder, adsorbent, paper production), culture …

•Calcium bentonite has much lower absorption properties and generally flakes off. Also known as "nonswelling bentonite". •Calcium bentonite is the most common type found in the world. •Calcium bentonite can be converted into sodium bentonite through sodium activation. (Calcium ions are exchanged for sodium carbonate.) Types of Bentonite

activated Iraqi Ca- bentonite / western desert in Iraq with two methods, direct and indirect activation after grinding the raw Ca-bentonite to powder, sieved and dried in oven at 180oC for 12 hrs. The direct activation included the addition of various concentrations of NaOH directly to 22.5 g of Iraqi bentonite and 350 ml of distilled water.

The activation process was carried out by mixing natural sorbent (Bentonite I) with an aqueous solution of sodium chloride (POCh, Gliwice, Poland). To examine the effect of various sodium concentrations, different NaCl concentrations were used (0.5, 1.0, and 2.0 mol/L).

mixing rather than grinding conditions. Its dispersion does, however, require some minimal shear (minimum tip speed 4 m/s when a dissolver is used). The paint to which it is to be added should have good movement in the letdown tank as BENTONE SD-1 additive is sifted in. Sufficient time for full activation should be allowed. The amount of time

The acid treatment for the bentonite activation also induced changes in some physical features . The acid treatment greatly affects both the bulk and surface properties of the clay mineral, inducing decreases in the humidity factor from 18 to 12% and in the cations exchange capacity from 67.5 to 48.2 meq per 100 g dry bentonite mainly due to ...

Acid activation (3 N) of M1 at different activation times (2, 4, and 6 h) and at different temperatures (25, 50, 75, and 90 °C) is able to change the physicochemical properties by increasing their surface areas. At four hours of activation, it is possible to give clays whose surfaces were the highest (between 368 and 659 m 2 /g).

The bentonite is a widely available and abundant natural mineral, and can be a low cost adsorbent for water and wastewater treatment. This study reported here was directed towards identifying a cost-effective activation protocol for enhancing the adsorption capacity of Australian bentonite for removal of toxic contaminants in wastewater.

Bentonite is usually found in its Ca form with lower CEC, which is an essential property for many applications. To improve CEC, Na-activation is a promising method to enrich bentonite with Na cations without any structural damages [8]. Furthermore, the Na-activation could help to separate the montmorillonite layers
