“…From conducted experiments, it could be concluded that BY28 and BR46 inclined to be adsorbed at lower temperature and that sorption process was exothermic. The exotermic sorption of dyes on methacrylic acid based sorbents (or similar systems) appeared to be common behavior and it was followed by to the heat released after bond formation between solute and sorbent [22,[38][39][40]. The similar sorption trend was observed for sorption of BY28 and BR46 onto PMAA, PAMPS and P(MAA-co-AMPS) hydrogels.…”

“…In our previous work we investigated sorption of Basic Yellow 28 on PMAA hydrogels and results have shown that at room temperature the percent of dye removal was only 76% [21]. PMAA modified biomass was used for removal of methylene blue, rhodamine B and basic magenta [22], poly(N-vinylpyrrolidone-co-methacrylic acid) hydrogels for removal of methyl violet [23] and (poly(methacrylic acid)-graftcellulose/bentonite) for removal of methylene blue [24].…”

“…The peaks at 1536 and 1242 cm −1 are attributed to C-N stretching (Choi and Yun 2006). The peak at 1402 cm −1 can be assigned to C=O symmetric stretching in carboxylate ions (Yu et al 2009). In addition, absorption peaks around 1157 cm −1 (P=O stretching) and 1067 cm −1 (P-OH stretching) were observed (Kim et al 2015).…”

“…According to the FT-IR results of RB (Fig. 1a), various adsorption peaks were observed at around 3600-3200, 1661,1536,1402,1242,1157, and 1067 cm −1 owing to multifarious functional groups on the surface of biomass (Yu et al 2009). The absorption peaks in the range 3200-3600 cm −1 overlapped the IR peaks for -OH groups and the -NH asymmetric stretching of amine groups on the biomass (Fang et al 2009).…”

“…Recently, as per the acquired knowledge on biosorption mechanisms, various methods of functional group modification such as addition of binding sites, removal of interfering sites, and coating/composite with ionic polymers have been applied to improve the sorption capacity (Kim et al 2016a). Among these modification methods, cases of the sorbents-applied ionic polymers such as polyethylenimine (PEI) (Cho et al 2016), poly(allylamine hydrochloride) (PAA HCl) (Mao et al 2010), and poly(methacrylic acid) (PMA) (Yu et al 2009) showed a drastic enhancement in the sorption capacity because ionic polymers possess a large Electronic supplementary material The online version of this article (https ://doi.org/10.1007/s1009 8-018-1542-2) contains supplementary material, which is available to authorized users.…”

In the present study, the relationship between the amount of anionic or cationic binding sites and adsorption capacities of biosorbents is discussed through potentiometric titration and mathematical model equations (proton-binding models). The poly(acrylic) acid-modified biomass (PAAB) and polyethylenimine-modified biomass (PEIB) derived from raw biomass (RB) Corynebacterium glutamicum (C. glutamicum) were used as cationic and anionic binding site-enhanced biosorbents, respectively. To obtain the sorption capacities of biomasses for anionic and cationic pollutants, isotherm tests were carried out using Basic Blue 3 (BB3, at pH 9) and Reactive Red 4 (RR4, at pH 2) as model anionic and cationic pollutants, respectively. The maximum sorption capacity (q m ) of PAAB was 1.28 times higher than RB for BB3. In the case of PEIB, the sorption capacity was found to be 3.27 times higher than RB for RR4. A quantitative information of functional groups could be estimated by the application of proton-binding models to potentiometric titration results. In addition, the buffering capacities of functional groups were obtained from the parameters of pK models. An increasing ratio of sorption capacities was similar to that of the buffering capacities of modified biosorbents obtained from all conditions of pK models. Therefore, the fact that the sorption capacity of modified biomass can be predicted by comparing it with the buffering capacity of biosorbents was confirmed.

Different sizes of epichlorohydrin‐crosslinked carboxymethyl cellulose (E/CMC) microspheres were successfully prepared by an inverse suspension method. With further modification by monochloroacetic acid (MCA), MCA–E/CMC microspheres were successfully synthesized. The structures and morphologies of these microspheres were analyzed with polarizing microscopy, scanning electron microscopy, ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy, Brunauer–Emmett–Teller analysis, and laser particle ζ‐potential recording. The adsorption properties of the microspheres were investigated with methylene blue (MB) as a model pollutant. The highest adsorption amount of MB (998.2 mg/g) onto MCA–E0.7/CMC which was the samples which treated with 0.7 mL of C4H9OH was obtained. Meanwhile, the effect of the operating parameters, such as the contact time, initial pH of the solution, temperature, and initial dye concentration, on the adsorption amount and MB removal were systematically studied. The results show that pseudo‐second‐order kinetic model provided the best correlation with the experimental data for the adsorption of MB onto the MCA–E0.7/CMC microspheres. Both the physical and chemical adsorption played the main role in the adsorption process. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44363.
