“…In order to further improve the adsorption amount, the adsorbent can usually be modified with much more functional groups to form polymer brushes [ 38 , 39 , 40 ]. Among the grafting methods, the surface-initiated atom transfers radical polymerization (SI-ATRP) technique is a ‘living’/controlled polymerization method which can provide much denser polymer brushes on the substrates.…”

Poly(2-(dimethylamino)ethyl methacrylate)-grafted bentonite, marked as Bent-PDMAEMA, was designed and prepared by a surface-initiated atom transfer radical polymerization method for the first time in this study. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA) were applied to characterize the structure of Bent-PDMAEMA, which resulted in the successful synthesis of Bent-PDMAEMA. As a cationic adsorbent, the designed Bent-PDMAEMA was used to remove dye Orange I from wastewater. The adsorption property of Bent-PDMAEMA for Orange I dye was investigated under different experimental conditions, such as solution pH, initial dye concentration, contact time and temperature. Under the optimum conditions, the adsorption amount of Bent-PDMAEMA for Orange I dye could reach 700 mg·g−1, indicating the potential application of Bent-PDMAEMA for anionic dyes in the treatment of wastewater. Moreover, the experimental data fitted well with the Langmuir model. The adsorption process obeyed pseudo-second-order kinetic process mechanism.

“…These results suggest that PAT‐TFP has good potentiality for the removal of various organic contaminants from water. The present PAT‐TFP material shows higher adsorption capacity than related Schiff base sorbents like porous organic polymers and gels, nanohybrid and composite materials, and covalent organic frameworks (Table S1, Supporting Information). Moreover, PAT‐TFP absorbs both anionic and cationic dyes probably due to the electrostatic, hydrogen bonding, and coordinated interaction on the acylhydrazone part.…”

Gel adsorbents are promising for pollutant removal from the wastewater. Herein, an acylhydrazone gel is developed from acylhydrazide‐terminated pentaerythritol (PAT) and 2,4,6‐triformylphloroglucinol (TFP) based on dynamic covalent acylhydrazone chemistry. PAT‐TFP gel is stable under various conditions, while it shows reversible Cu 2+ adsorption and desorption. PAT‐TFP gel is studied as a versatile adsorbent for the capture of a range of (bulky) organic contaminants and heavy metal ions from aqueous solutions. Fast and good adsorption capacities are achieved for various dyes (rhodamine B and methyl orange), amines (aniline, p ‐chloroaniline, 4‐methylaniline, and p ‐aminobenzoic acid), phenols (phenol, 1‐naphthol, p ‐methylphenol, and bisphenol A), and metal ions (Cu 2+ , Cr 3+ , and Hg 2+ ). The maximum adsorption capacity is 107.5 mg g −1 for Cu 2+ and the equilibrium adsorption time is 30 min. PAT‐TFP gel can be regenerated efficiently and used repeatedly.

“…To address the need for adsorbent materials with a huge surface area, plenty of functional groups and open porosity, maximizing the adsorption efficiency and rate, Ou et al [46] synthesized a rich amine porous organic polymer (RAPOP) via the Schiff base reaction. The nanoparticles made of such a polymer possess a large number of micro/mesopores formed via the polymerization reaction between melamine and terephthalaldehyde monomers.…”

Clean water is a vital element for survival of any living creature and, thus, crucially important to achieve largely and economically for any nation worldwide. However, the astonishingly fast trend of industrialization and population growth and the arisen extensive water pollutions have challenged access to clean water across the world. In this regard, 1.6 million tons of dyes are annually consumed. Thereof, 10%–15% are wasted during use. To decolorize water streams, there is an urgent need for the advanced remediation approaches involving utilization of novel materials and technologies, which are cost and energy efficient. Nanomaterials, with their outstanding physicochemical properties, can potentially resolve the challenge of need to water treatment in a less energy demanding manner. In this review, a variety of the most recent (from 2015 onwards) opportunities arisen from nanomaterials in different dimensionalities, performances, and compositions for water decolorization is introduced and discussed. The state-of-the-art research studies are presented in a classified manner, particularly based on structural dimensionality, to better illustrate the current status of adsorption-based water decolorization using nanomaterials. Considering the introduction of many newly developed nano-adsorbents and their classification based on the dimensionality factor, which has never been employed for this sake in the related literature, a comprehensive review will be presented.
