“…Interactions between the HCl–FA molecules and HCl–resin were the most probable reasons for the lesser efficiency at the lower pH value. This trend is consistent with the reports previously published in the literature. ,,, Lin et al (2016) also stated that the authors reached the maximum adsorption capacity at the natural pH of the FA solution …”

“…This means that below pH = 3.75, most of the FA molecules in the solution are undissociated, whereas above that value, they are dissociated. As it is known, the mechanism for the adsorption process changes depending on the resin basicity. ,,, With a weak basic AER, the mechanism is based on the adsorption of the undissociated forms of acid on the resin. On the other hand, with a strong basic AER, it becomes an anion-exchange process between the dissociated form of the target acid in the solution and the functional group of the resin.…”

“…In the literature, several researchers studied about the recovery of CAs from fermentation broth such as lactic acid, − succinic acid, and butyric acid using various types of anion-exchange resins (AERs). In addition, separation of acetic, , levulinic, fumaric, lactic, , itaconic, citric, , and succinic ,, acids from aqueous solutions using commercially available resins produced by different companies were reported. Some researchers also studied the recovery of acids from multiacid aqueous solutions. , …”

Wastewaters containing organic compounds such as acids, ketones, phenols, and amines can cause critical environmental problems depending on their concentration and composition. Efficient and low-cost separation of these components may also bring their reuse in industry while cleaning the aqueous streams. Formic acid (FA) is an important raw material in industry and is widely seen in wastewaters. In this study, two different anion exchangers were compared for the separation of FA from aqueous solutions. Effects of process parameters and the mechanism were discussed. Kinetic, equilibrium, and thermodynamic studies were performed, and the data were interpreted using the relevant isotherm and kinetic models. The results showed that Lewatit MP-64 was more efficient than Amberlite IRA-96 in the range of the parameters studied. The maximum adsorption capacity obtained with Lewatit MP-64 (442.75 mg/g) was significantly higher than that were previously reported in the literature for FA separation. The data were well explained by the Langmuir isotherm model. However, relatively high R 2 values were obtained with Temkin and Freundlich isotherms. Therefore, further studies are ongoing to clarify the mechanism.

“…To evaluate the adsorption rate behavior for MPD onto the adsorbents at 303 K, pseudo‐first‐order rate, pseudo‐second‐order rate, and intraparticle diffusion models were employed to fit the kinetic data. The kinetic equations are as follows:

q_{t} = q_{e} ([], 1 - \exp ((), - K_{1} t))

\frac{t}{q_{t}} = \frac{t}{q_{e}} + \frac{1}{K_{2} q_{e}^{2}}

q_{t} = K_{d} t^{1 / 2} + C

Four kinds of hypercrosslinked resins (acidic resins labeled SAMR and TAMR and heterocyclic resins IDLMR and PRLMR) were synthesized as adsorbents to remove m-phenylenediamine (MPD) from aqueous solution comparably. The Brunauer-Emmett-Teller specific surface area and pore size distribution of the two types of resins have been compared, and the infrared spectra of the resins confirm the presence of the modified groups. The adsorption isotherms illustrate that the Freundlich equation fits more appropriately than the Langmuir equation or the Temkin equation. In addition, the kinetic curves indicate that the pseudo-second-order model is a better fit than the pseudo-first-order model. The thermodynamic studies show that the isosteric adsorption enthalpy changes (ΔH) and the Gibbs free energy change (ΔG) are both negative, revealing that all of the adsorption processes are spontaneous and exothermic. All of the modified resins exhibit the best adsorption capacity at pH = 6.24. The results show that the acidic resins have better adsorption of MPD.

In this study, the adsorption/desorption characteristics of rapeseed meal polysaccharides extract on four resins (HP‐20, D3520, XAD‐16, and AB‐8) were evaluated. The results indicated that HP‐20 resin had the best purification effect. Based on static adsorption test, the kinetics and isotherms of the four resins for protein and polysaccharide were investigated. The adsorption test showed that the pseudo‐second‐order kinetics model and the Freundlich isotherm model were more suitable for explanation of the adsorption process for protein and polysaccharide. Static desorption test showed that the highest protein desorption ratios of HP‐20, D3520, and AB‐8 resins could be obtained with 60% ethanol solution as eluate, and the highest protein desorption ratios of XAD‐16 resin could be obtained with 40% ethanol solution as eluate. Dynamic adsorption/desorption tests of HP‐20 resin showed that the deproteinization ratio was 91% and the polysaccharide recovery ratio was 62% when the treatment amount was 1.5 BV. Compared with three traditional methods, HP‐20 resin adsorption method that the deproteinization ratio was 82% was more potent than the three traditional methods for purifying polysaccharides from rapeseed meal. In addition, UV/vis spectroscopy showed that most of the protein was absorbed by resins, and FT‐IR spectroscopy indicated that the purity of the polysaccharide after purification was improved. Rapeseed meal polysaccharides could be effectively deproteinized using HP‐20 resin, and it was suitable for purifying polysaccharides from rapeseed meal.
