“…These could be attributed to electrostatic repulsion between negatively charged FQs and negatively charged nanocomposite. Several researchers in the literature have observed similar findings with respect to the adsorption behavior of FQs at low and high pH values [61,[65][66][67][68][69][70][71]73,74]. The results for the effect of sonication power level are shown in Figure 5B,C; it was not significant at the 95% confidence level.…”

“…To compare the performance of the nanocomposite for the adsorption of FQ antibiotics, adsorption capacities of DANO, ENRO and LEVO on various adsorbents is presented in Table 7. As observed in Table 7, the adsorption capacity of the nanocomposite was comparable even better than other adsorbents reported elsewhere [25,61,65,67,[69][70][71]74]. However, the adsorption capacity was lower than those reported by references [66,73].…”

“…Consequently, the adsorption mechanism is also dependent on the adsorbent surface charge. For instance, the FQ antibiotics can be adsorbed by a negatively or positively charged adsorbent using cation exchange through protonation of amine group or electrostatic interaction due to the deprotonation of carboxylic groups [39,61,[65][66][67][69][70][71][72].…”

The application of a magnetic mesoporous carbon/β-cyclodextrin–chitosan (MMPC/Cyc-Chit) nanocomposite for the adsorptive removal of danofloxacin (DANO), enrofloxacin (ENRO) and levofloxacin (LEVO) from aqueous and environmental samples is reported in this study. The morphology and surface characteristics of the magnetic nanocomposite were investigated by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) adsorption–desorption and Fourier transform infrared spectroscopy (FTIR). The N2 adsorption–desorption results revealed that the prepared nanocomposite was mesoporous and the BET surface area was 1435 m2 g−1. The equilibrium data for adsorption isotherms were analyzed using two and three isotherm parameters. Based on the correlation coefficients (R2), the Langmuir and Sips isotherm described the data better than others. The maximum monolayer adsorption capacities of MMPC/Cyc-Chit nanocomposite for DANO, ENRO and LEVO were 130, 195 and 165 mg g−1, respectively. Adsorption thermodynamic studies performed proved that the adsorption process was endothermic and was dominated by chemisorption.

“…Many approaches have been carried out to improve the physicochemical properties of CTS such as crosslinking reaction [19], grafting with amino functional groups [20], and compositing with nanomaterials [21]. Amongst the approaches, crosslinking reaction is the most convenient pathway for developing attributes of CTS such as its mechanical strength, solubility in acidic medium, chemical stability and hydrophobicity [22,23].…”

Cross-Linked Chitosan-Glyoxal/Kaolin Clay Composite: Parametric Optimization for Color Removal and COD Reduction of Remazol Brilliant Blue R Dye

et al. 2021

View full text Add to dashboard Cite

Kaolin clay (KN) was employed as an inorganic filler to modify a cross-linked chitosan-glyoxal as Schiff's-based chitosan composite derivative (CTS-GLY). The resulting (CTS-GLY/KN) was found to be a promising composite synthetic biopolymer that can be potentially utilized for color removal as well as COD reduction of an industrial anionic dye (remazol brilliant blue R, RBBR). The surface porosity, crystallinity, morphology, functionality, charge, and amine content of the CTS-GLY/KN were studied using BET, XRD, SEM, FTIR, pHpzc and pH-potentiometric titration analyses, respectively. Response surface methodology-Box-Behnken design (RSM-BBD) was used to optimize the impact of the main input factors on the color removal and COD reduction of RBBR. The adsorptive performance CTS-GLY/KN towards RBBR was well-defined by both Langmuir and Freundlich isotherm models with highest adsorption capacity of 447.1 mg/g at 30 ˚C. This finding reveals that CTS-GLY/KN can be utilized as a promising, feasible, and environmentally friendly composite-biosorbent for color removal and COD reduction of textile dyes from aqueous medium.

Antibiotics along with their metabolites due to their toxicity and low biodegradability have adverse effects to human and animal health. This work can help to monitor and elimination of the residue of the cloxacillin (Clox) antibiotics in two ways: the first part involves design and fabrication of a new electrochemical nanosensor based on a screen-printed carbon electrode modified with gold nanourchin and graphene oxide for detection and determination of Clox in aqueous media. The second part focuses on the preparation of carbon nanocomposites modified with multi-walled carbon nanotubes (MWCNT/CC) as adsorbent for the removal of Clox from aqueous medium. The MWCNT/CC nanocomposites were made using sol-gel process and then the efficiency of the antibiotic removal was assessed by the designed nanosensor. In Clox removal experiments, the effect of independent variables including pH, exposure time, extent of MWCNTs and amount of adsorbent on the removal of antibiotic as a dependent variable was investigated using response surface methodology. The morphological and physical properties of the suggested adsorbent were explored. The maximum efficiency of Clox removal (97%) was achieved in conditions of using 1.52 g/L of the adsorbent fabricated by 2.9 wt. % of MWCNTs in 0.1 M phosphate buffer solution at pH of 5.0 during 75 minutes. The highest adsorption capacity of the MWCNT/CC was 296 mg/g at optimal conditions.
