“…Meanwhile, DCP has been used as a precursor for the synthesis of herbicides and pesticides [8,9]. There is a recurring presence of these compounds in water bodies due to frequent use, which has lead to accumulation in the environment causing serious pollution problems [6,7,[10][11][12][13]. It has been found that at low concentrations, these compounds are highly toxic, poorly biodegradable and present carcinogenic properties.…”

Pillared clay based composites containing transition metals and a surfactant, namely MAlOr-NaBt (Bt=bentonite; Or=surfactant; M=Ni(2+), Cu(2+)or Co(2+)), were prepared to study selectivity and capacity toward single and multiple-component adsorption of bisphenol A (BPA) and 2,4-diclorophenol (DCP) from water. Tests were also performed to account for the presence of natural organic matter in the form of humic acid (HA). Equilibrium adsorption capacities for single components increased as follows: NaBt

“…Several physicochemical processes have been proposed as alternatives to reduce or eliminate these contaminants [11,13]. Amongst these, separation via adsorption has proven promising due to its efficiency in pollutant removal at low concentrations, simplicity of design, low operational cost, and absence of toxic by-products [20][21][22].…”

“…BPA is a compound widely used in plastics, construction, and paintings sectors that has been detected in water and food. [76,77] Human exposure to this kind of compound can lead to hormonal disruption, and it has consequently received much attention as an emerging contaminant of concern from regulatory bodies and the industrial world in recent years. [78,79] As shown in Figure 9a, the grafting of CTS with P4VP strongly improved the ability of the material to interact with BPA.…”

in various fields including, water and wastewater treatment as adsorbents or coagulation-flocculation agents, medical applications as drug delivery systems, and the cosmetic or agriculture sectors. [2,4,8] However, the properties of unmodified CTS limit its use for some applications. Consequently, researchers have focused on the modification of CTS to improve and tune its properties, such as improved solubility in organic solvents, compatibility with various polymers, or affinity for molecules of interest. Possible chemical modifications of CTS include acylation, alkylation, quaternization, azidation, and phosphonation, [9-19] as well as the grafting of polymers. [20,21] One of the incentives for modifying CTS is to enhance its solubility in organic solvents for the preparation of advanced materials requiring chemical modification in specific solvents. For this purpose, N-phthaloylation was described by Kurita et al. using a method that involved the presence of small amounts of hydroxy-containing compounds for selective N-phthaloylation while avoiding O-6 phthaloylation. [22-24] N-phthaloylation with a high degree of substitution was prepared in acidic aqueous media by Ifuku et al. [25] The same group also successfully prepared N-(4-bromophthaloyl) chitosan exhibiting high solubility in common solvents, such as dimethylsulfoxide (DMSO), N,N-dimethylformamide (DMF), N,N-dimethylacetamide, and N-methylpyrrolidone (NMP). [9] The alkylation of CTS was reported in heterogeneous and homogeneous conditions for the introduction of specific chemical groups, such as aromatic structures, imidazole, sulfonate, or carboxylation. [26-31] Complexation of CTS with surfactants, such as sodium dodecylsulfate or sodium dodecylbenzenesulfonate was also described as a method for improving its solubility in organic solvents. [32-35] The grafting of synthetic polymers on CTS is a powerful and flexible tool among the strategies for preparing innovative materials. [20] Most reports on CTS modification by grafting have examined the use of free radical polymerization, [36-39] ring-opening polymerization, [40,41] γ-radiation, [38,40] or cationic polymerization [37,42] via both "grafting from" and "grafting to" approaches. Controlled radical polymerization, now more commonly known as reversible deactivation radical polymerization (RDRP), has provided a versatile tool for designing new CTSbased materials grafted with well-defined and functional (co) polymers. Atom transfer radical polymerization (ATRP) [43-51] Spherical macroscopic particles (beads) made from chitosan (CTS), a polysaccharide derived from the valorization of food waste, are converted into a biohybrid material by grafting poly(4-vinylpyridine) (P4VP) using a "grafting from" approach via reversible addition-fragmentation chain-transfer (RAFT) polymerization. Varying the time of reaction, and therefore the conversion, allows to readily tune the composition (CTS vs synthetic polymer content) and consequently the bead properties. P4VP has specific affinity for certain compounds. Th...

“…2,4-D is commonly used to control broad-leaf weeds and grass in wheat, maize, oat, rye and cane crops due to its good selectivity and low cost (Aksu and Kabaskal 2005;Salmon and Hameed 2010). The half-life of 2,4-D, which is applied at between 50 and 100 L ha -1 in aerobic and anaerobic aquatic environments, has been estimated to be 15 days and 41-333 days (Aksu and Kabaskal 2004;. Liang et al 2015).…”

The potential of a granular activated carbon (GAC), a rice husk biochar (BRH) and multiwalled carbon nanotubes (MWCNTs) for removing 2,4-dichlorophenoxyacetic acid (2,4-D) from simulated wastewater and drainage water has been evaluated. In this regard, a response surface methodology (RSM) with a central composite design (CCD) (CCD-RSM design) was used to optimize the removal of 2,4-D from simulated wastewater under different operational parameters. The maximum adsorption capacities followed the order GAC > BRH > MWCNTs, whereas the equilibrium time increased in the order MWCNTs < GAC < BRH. In the case of GAC and BRH, the 2,4-D removal percentage increased significantly upon increasing the adsorbent dosage and temperature and decreased upon increasing the initial 2,4-D concentration and pH. The results showed that the contact time and temperature were not important as regards the adsorption efficiency of 2,4-D by MWCNTs, whereas rapid removal of 2,4-D from simulated wastewater was achieved within the first 5 min of contact with the MWCNTs. The results confirmed that the Freundlich isotherm model with the highest coefficient of determination (R 2 ) and the lowest standard error of the estimate (SEE) satisfactorily fitted the 2,4-D experimental data. In addition, successful usage of the three adsorbents investigated was observed for removal of 2,4-D from drainage water from an agricultural drainage system. An economic analysis with a rate of return (ROR) method indicated that BRH could be used as an eco-friendly, low-cost, versatile and high adsorption capacity alternative to GAC and MWCNTs for the removal of 2,4-D.
