“…In general, it is considered that inorganic anions of salts may compete for active sites on the adsorbent surface or deactivate the adsorbent [15]. A similar effect was observed for low concentration of electrolyte in the case of OG adsorption on mesoporous carbon.…”

“…Of the commercial resins, the weak basic type (MP62, Bayer) showed the most favourable profile for reactive dyes: maximum loadings (230-900 mg g −1 ) and complete regeneration [14]. The adsorption capacity of various synthesised polymeric adsorbents can be improved using monomers which have functional groups such as amino groups due to the specific interactions of these groups bound to the polymeric matrices with certain types of dyes [15].…”

The performance of a weak base anion-exchange resin in removing Orange G dye from aqueous solutions in batch and column system was investigated. The adsorption capacity was found to depend on: pH, dye concentration, contact time, adsorbent dosage, electrolyte presence and temperature. The adsorption equilibrium is best described by the non-linear Langmuir isotherm model. At the optimum pH of 2, the maximum adsorption capacity was 1,076 and 1,218 mg g −1 , at 20 and 50˚C, respectively. The adsorption kinetics could be described by the pseudo-second-order reaction model. The thermodynamic parameters indicated that adsorption is a spontaneous and endothermic process. FT-IR and SEM analyses provided additional information on adsorption mechanism and on morphological changes of the adsorbent. The breakthrough experimental results were processed by means of Thomas, Yoon-Nelson and Wolborska models. The reusability of the column was examined by conducting several cycles of adsorption and desorption (with 0.05 M NaOH).

“…In turn, after electro-polymerization, a linear growth has also been reported for this compound 7,[28][29][30][31] allowing thus to go deeper into its guiding and stabilizing properties in polymeric matrices obtained once the copolymer has been synthesized; [17][18][19]28,32 this helps to improve redox signals, coatings quality, pH stability, 27 and so on. Consequently, the goal of this work is the obtention of a novel copolymer, made of OPD and 1AAQ, hoping that synergistic effect enables the synthesis of a material with the properties of each homopolymer; these features would confer interesting projections as electrochemical sensor, being thus essential its obtention directly on an electrodic substrate that in this case, owing to its low cost, would be stainless steel, SS.…”

Poly(1-amino-9,10-anthraquinone-co-o-phenylenediamine) (P1AAQ-co-POPD) was synthesized by electrochemical methods on stainless steel electrodes (SS) using equal monomer concentration in acetonitrile/acidified water mixture as solvent. Electrochemical characterization allows, among others, determining the characteristic redox couple potential of the quinone group, which is one of the advantages of having achieved the copolymerization. FTRaman, ATR and UV-Vis characterization confirms the formation of the copolymer, particularly, by the occurrence of a novel signal ascribed to a new C-N type bond. Besides, the conductivity of the deposits was determined, which enabled the conducting properties of the products to be verified. The topographical and morphological characterization accomplished by atomic force (AFM) and transmission electron (TEM) microscopy showed how the inclusion of o-phenylenediamine (OPD) increases the homogeneity of the copolymer, which in turn enables designing likely applications of the electrode modified with this novel polymeric material.

“…Graft copolymers of acrylic acid have received much attention because of their increased industrial potential [15,16]. In hoping to find more application for KGM, in this work the synthesis of a new polysaccharide-based superabsorbent hydrogel via graft copolymerization of acrylic acid onto KGM is presented.…”

A novel konjac glucomannan (KGM)‐acrylic acid‐diatomite composite (KGAD) was synthesized by the solution polymerization of partially neutralized acrylic acid (AA) on to KGM and diatomite (DT), using potassium persulfate as a free radical initiator, in the presence of Trimethylolpropane Trimethacrylate (TPTA) as a crosslinking agent. The structure and morphology of KGAD were characterized by using FT‐infrared, X‐ray diffraction, scanning electron microscopy. Besides, the thermal stability as well as the salt absorption of the composites was investigated by the thermogravimetric analysis and the swelling rate test, respectively. The results showed that the interactions between KGM‐AA (KGA0) and DT could be generated through hydrogen bond formation. Besides, the crystal of composites became rules and grew well with the addition of DT. It was also found that the appropriate amount of DT could be dispersed uniformly with a single crystal state in the matrix of KGA0 while excessive DT caused aggregation, inducing an irregular distribution in the matrix. In addition, the thermal stability of KGAD was improved based on the introduction of DT into the polymer network. POLYM. COMPOS., 37:3384–3390, 2016. © 2015 Society of Plastics Engineers
