In this study, bentonite-supported nanoscale zero-valent iron (B-nZVI) was used as a catalyst to activate persulfate (PS) for the simultaneous removal of Cr(VI) and phenol from aqueous solutions. Experimental results indicated that the presence of bentonite could decrease the aggregation of nZVI and increase its reactivity. The removal rates of Cr(VI) and phenol by B-nZVI system were 99.90% ...

10-03-2021· Should such pollutants reach water courses, processes such as eutrophication and death of aquatic life could result(1). Some of the leading, and robust, treatments of oily and heavy metal contamination in water and waste storage are based around bentonite and anthracite.
Bentonite is used in retention systems and for the control of stickies and pitch. Furthermore it helps to improve the loop water treatment which reduces the water consumption. Bentonite is ideal for use in litter due to its unique water absorption, swelling, and odor controlling properties. It is an excellent anti-caking agent for animal feed.

Additionally, compared to the 0% CBC treatment (11.81 ± 0.57-25.75 ± 0.89 mg/kg), the Ca-bentonite amendments showed a positive effect on restraining the diethylene triamine penta-acetic acid Zn mobilization (4.43 ± 0.41-12.48 ± 2.54 mg/kg) in pakchoi and Chinese cabbage; beside this, no obvious effect was observed on DTPA-Cu.
Bentonite — Wikipédia. La bentonite est une argile colloïdale dont le nom vient de Fort Benton dans le Wyoming aux États-Unis. Connue aussi sous le terme de terre à foulon, elle peut être considérée comme une smectite, étant essentiellement constituée de montmorillonite (Na,Ca) 0.33 (Al,Mg) 2 Si 4 O 10 (OH) 2 (H 2 O) n (80 %) qui est une argile ce qui explique sa capacité de ...
