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.
Highlights
Zhang et al investigated the adsorption of Amido Black 10B from aqueous solutions onto a Zr (IV) surface-immobilized cross-linked chitosan/bentonite composite [4]
Compared with Bent, the adsorption amount of Bent-polyallyl amines (PAA) for AB10B obviously increased depended on the pH value
The characterization results of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM) demonstrated that PAA was modified successfully onto interlayers of bentonite
Summary
Zhang et al investigated the adsorption of Amido Black 10B from aqueous solutions onto a Zr (IV) surface-immobilized cross-linked chitosan/bentonite composite [4]. Zhang et al prepared a crosslinked quaternized chitosan/bentonite composite for the removal of Amino black 10B from aqueous solutions [6]. For use in practical applications, Li et practical applications, Li et al prepared a chitosan magnetic composite adsorbent modified withal. A prepared a chitosan magnetic composite adsorbent modified with a orange quaternary ammonium saltThis for quaternary ammonium salt for the removal of Cr(VI). The reason might be natural Bent has limited adsorption capability, which restricts its practical applications [24]. Bent should be modified with some improve itsgroups adsorption capability for dyes. The novel material was used to adsorb Amido Black 10B as a representative of the anionic dyes.
