Adsorption of poly(4-vinylpyridine) onto bentonites

Removal of basic dye using raw and acid activated bentonite samples

“…Adsorption process provides an attractive alternative treatment to other removal techniques because it is more economical and readily available. Bentonite is widely applied in many fields of adsorption technology including the removal of metals [2,3], phenols [4,5], organic molecules [6,7], polymers [8,9], pesticides [10], radionuclides [11], and dyes [12,13].…”

Removal of basic dye by modified Unye bentonite, Turkey

“…Bentonite is widely applied in many fields of adsorption technology including the removal of metals [3,4], phenols [5][6][7], organic molecules [8,9], polymers [10,11], pesticides [12], radionuclides [13], and dyes [14,15]. A composite adsorbent, manganese oxidemodified bentonite (MMB), was proposed and studied in this research.…”

Adsorption of Acid Blue 193 from aqueous solutions onto Na–bentonite and DTMA–bentonite

“…Due to the weak interactions between the negatively charged surface in clays and anionic dyes, a limited number of studies on the adsorption of acid dyes have been carried out using bentonite as an adsorbent [18][19][20], but none of them has investigated adsorption of Acid Blue (AB193) dye onto Nabentonite and DTMA-bentonite. In addition, this kind of clay is largely used in industrial products such as ceramic paint, coatings, and drilling mud [21]. Bentonite is mainly composed of montmorillonite, which is a 2:1-type aluminosilicate.…”
