“…The broad and sharp narrow peak indicates that PnSA is partly crystalline and partly amorphous and, thus, is expected to have high adsorption properties. The results are consistent with previous studies that reported similar nature of polyaniline composites . However, after Remazol dye adsorption, the sharp narrow peaks disappeared.…”

Benzenesulfonic acid‐doped polyaniline nanorods were synthesized by oxidative polymerization of aniline and were subsequently used for the decolorization of simulated reactive dye bath effluent. Transmission electron micrograph showed that the size of the nanorods varied from 60 to 90 nm. Fourier transform infrared pattern of nanorods indicate that sulfonic acid was successfully doped on polyaniline nanorods. Under optimized conditions, sulfonic acid doped polyaniline nanorods decolorized 78% of simulated reactive dye bath effluent. The modified Freundlich model and modified pseudo‐first‐order model showed satisfactory fit for dye decolorization. The crystalline nature of the nanorods was modified after adsorption of dyes. The results of the study indicate that benzenesulfonic acid doped polyaniline could be used for the treatment of textile wastewaters. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1383–1389, 2017

“…In recent years, the safety of adsorbents themselves has received great attention with increasing awareness of environmental protection. Biomass‐based adsorbents, such as cellulose‐, starch‐ and chitin‐based adsorbents have been widely researched . As a type of reproducible resource, cellulose is rich in nature and shows biodegradable, nontoxic, and inexpensive features.…”

Betaine‐modified cationic cellulose was prepared through the reaction of cellulose with betaine hydrochloride by an efficient one‐step dry method. Dicyandiamide was used as a dehydrating agent to promote the formation of ester bonds between the reactants. Fourier transform infrared spectroscopy, X‐ray diffraction, and scanning electron microscopy were used to characterize the cellulose betainate. Experiments showed that at a molar ratio of the cellulose glucose unit, betaine hydrochloride to dicyandiamide, of 1:1:0.5 at 150°C for 3 h, the degree of substitution of the cationic group reached 0.80. The adsorption of simulated C. I. Reactive Red 24 and C. I. Reactive Red 195 wastewater on the cationic cellulose was carried out, and the effects of the adsorbent dose, initial dye concentration, and salt concentration on the dye removal efficiency were investigated. The equilibrium adsorption isotherm data of the cationic cellulose exhibited a better fit to the Langmuir isotherm model than the Freundlich one. The experimental results suggest that the prepared cationic cellulose materials show potential application for reactive dye wastewater treatment. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

“…6). The peaks at 3419 and 3126 cm -1 could be assigned to N-H and O-H stretching of polymeric compounds, respectively, present in the peat moss (Gardea-Torresdey et al 1996;Shin et al 2012;Janaki et al 2013). The troughs that were observed at 2923, 2852, 1375, and 1319 cm -1 indicated the presence of C-H groups.…”

The aim of this study was to assess the potential of Indian Sphagnum peat moss, a widespread terrestrial bryophyte, for the uptake of Ni(II) ions from aqueous solution. Experiments were carried out as a function of contact time, pH, adsorbent dosage, and initial concentration of Ni(II). Batch experiment results showed that peat moss removed 99.5 % of Ni(II) from aqueous solution at pH 6. Freundlich model showed satisfactory fit to the equilibrium adsorption data of Sphagnum peat moss. The adsorption kinetics followed pseudo-second-order kinetic model, which demonstrates that chemisorption may be the rate controlling step in the adsorption of Ni(II) onto the Sphagnum peat moss. The interactions between the peat moss and Ni(II) were further studied by Fourier transform infrared spectroscopy.
