Bentonite Modified by Allylamine Polymer for Adsorption of Amido Black 10B

Abstract

The main object of this work is to remove Amido black 10B using a new type of bentonite-based adsorbent with cationic groups by the modification of polyallyl amines between the interlayers of bentonite. Fourier transform infrared, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy were used to characterize the functionalized bentonite. A series of batch adsorption experiments were performed. The maximum adsorption amount was 144.08 mg g−1 when the pH was 2 and the contact time was 120 min. In addition, the equilibrium isotherm data were analyzed using Langmuir and Freundlich isotherm models, while only the Langmuir model could provide a high correlation. Therefore, this study provided a new functionalized bentonite as a low-cost adsorbent for dye removal from water.

Adsorption Evaluation for the Removal of Nickel, Mercury, and Barium Ions from Single-Component and Mixtures of Aqueous Solutions by Using an Optimized Biobased Chitosan Derivative

“…The main methods for the metal ions uptake from industrial wastewaters are reverse osmosis, solvent extraction, ion exchange, chemical precipitation, membrane filtration, electrolytic methods, and adsorption [ 16 , 17 , 18 ]. However, these techniques have high operational cost and in the case of trace level concentrations may be ineffective for the adsorption of some types of toxic metal ions [ 16 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Therefore, a candidate facing the heavy metal ions pollutions is the use of adsorption technology [ 35 , 36 , 37 , 38 , 39 ], and specifically by using chitosan as an adsorbent.…”

“…There are several adsorbents to eliminate contaminants, including bentonite/allylamine 19, magnetic bentonite 20, bentonite‐chitosan, bentonite‐chitin 21, AC/magnetite 9, 22, magnetic graphene/zeolite 23, and magnetic carbon microspheres 24.…”

Chitosan Grafted with Biobased 5-Hydroxymethyl-Furfural as Adsorbent for Copper and Cadmium Ions Removal

“…Finding a method that satisfies the combination of all issues as described above is of crucial importance. Recently, significant attention has been paid to adsorption technique [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], which are easily applied to the final stages of wastewater treatment plants (WWTPs), with the aim of removing all residues (ions) that were not separated and removed from the previous stages.…”
