“…Activated carbon and nonpolar or weakly polar porous polymer resins are the most common adsorbents [ 15 , 34 , 35 , 36 , 37 ]. Special attention is paid to the specific surface area, pore, and granule sizes of these adsorbents [ 38 ], as well as the temperature of the adsorption process [ 39 , 40 ]. A number of researchers also highlighted that the nature of the adsorbent can significantly affect the performance of the process [ 15 , 41 , 42 ].…”

This study examines the mechanisms of adsorption of anthocyanins from model aqueous solutions at pH values of 3, 6, and 9 by ion-exchange resins making the main component of heterogeneous ion-exchange membranes. This is the first report demonstrating that the pH of the internal solution of a KU-2-8 aromatic cation-exchange resin is 2-3 units lower than the pH of the external bathing anthocyanin-containing solution, and the pH of the internal solution of some anion-exchange resins with an aromatic (AV-17-8, AV-17-2P) or aliphatic (EDE-10P) matrix is 2–4 units higher than the pH of the external solution. This pH shift is caused by the Donnan exclusion of hydroxyl ions (in the KU-2-8 resin) or protons (in the AV-17-8, AV-17-2P, and EDE-10P resins). The most significant pH shift is observed for the EDE-10P resin, which has the highest ion-exchange capacity causing the highest Donnan exclusion. Due to the pH shift, the electric charge of anthocyanin inside an ion-exchange resin differs from its charge in the external solution. At pH 6, the external solution contains uncharged anthocyanin molecules. However, in the AV-17-8 and AV-17-2P resins, the anthocyanins are present as singly charged anions, while in the EDE-10P resin, they are in the form of doubly charged anions. Due to the electrostatic interactions of these anions with the positively charged fixed groups of anion-exchange resins, the adsorption capacities of AV-17-8, AV-17-2P, and EDE-10P were higher than expected. It was established that the electrostatic interactions of anthocyanins with the charged fixed groups increase the adsorption capacity of the aromatic resin by a factor of 1.8–2.5 compared to the adsorption caused by the π–π (stacking) interactions. These results provide new insights into the fouling mechanism of ion-exchange materials by polyphenols; they can help develop strategies for membrane cleaning and for extracting anthocyanins from juices and wine using ion-exchange resins and membranes.

Significant attention has been paid to contaminants of emerging concern (CECs) for several years due to their persistence in water sources and toxicity. The necessity of upgrading current wastewater treatment technologies is vital to guarantee timely remediation of CECs, particularly given the scarcity of potable water for direct human consumption and even for agricultural irrigation. In this regard, the integration of transition metals onto porous adsorbent materials for use in water and wastewater treatment operations could play a significant role due to their ability to undergo specific interactions (i.e., complexation-type) with CECs at ambient temperature. Furthermore, coupling these interactions with hydrophobicity inducing species or phases in situ (i.e. hierarchically) further enhances affinity and capacity toward CECs. This review highlights the progress so far in the bench-scale design of transition metal-based nanoporous adsorbents, including hierarchical composites prepared via confined space synthesis, for the removal of CECs from water at ambient conditions.

“…Also, resin [40,41] has many applications to treat and re-utilize waste water especially hyper-crosslinked resin which has a powerful ability for re-generation and high sorption's capacity [42][43][44]. The surface modifications, that can greatly improve the sorption selectivity, can develop custom-designed sorption resins with unique functional groups [3,[45][46][47][48]. David et al, 1998 [49] investigated the photochemical and ultrasonic degradation of CIPC and 3CA in aqueous solution.…”

Background: Chloroaniline is a crucial organic additive commonly applied in medicine, chemical industries, plastics and pesticides. Besides, it is also a widespread pollutant, which has a high degree of persistence, toxicity, accumulation and it is hard to be naturally degraded. Result: 3-chloroaniline (3CA) concentrations were measured in aqueous solution by UV/Vis spectrophotometer. Validation of the calibration curve's linearity, instrumental precision (RSD%), limits of detection and quantification were accomplished. The coefficient of calibration curve (1.0–10.0 mgL-1 3CA) had a high correlation (R² = 0.9997) and the instrumental precision was in the range (RSD% = 0.50–0.74%, n=10). The LOD and LOQ from the regression analysis were 0.20 mgL-1 and 0.61 mgL-1, respectively. A treated coffee waste adsorbent was utilized for 3-chloroaniline removal by process of sorption from aqueous solution. The major components of the coffee waste are the hemicellulose, cellulose, and lignin. The temperature effect (25°C, 35°C and 45°C) on sorption was evaluated, with sorption decreasing by increasing of temperature. Isotherms type L were found and associated with monolayer sorption. The parameters of sorption were examined by employing Langmuir, Freundlich and Dubinin-Radushkevich sorption models. The isotherm models of Langmuir and Dubinin-Radushkevich had acceptable correlation coefficients (R2). The Langmuir and Dubinin-Radushkevich sorption capacities of 3-chloroaniline were found to be 44 to 50 mgg−1. The values of separation factor (RL) were ranging from (0-1) which indicated a favourable sorption. In thermodynamic study the physical sorption process was confirmed by van’t Hoff equation. In addition, the free energy ∆G° and enthalpy ∆H° had negative values which suggested that the sorption was spontaneous, and the process was exothermic. Conclusion: Since the adsorbent used in this study is abundant and available, it is considered a potential adsorbent material for 3CA removal from aqueous fluids and suitable for the wastewater treatment.
