“…While MRES decomposes approximately 12% between 150–300°C, 21% between 300–410°C and it degrades 27% between 410–550°C, leaving almost the same amount of char as the RES. Initial decomposition temperature of RES, which was about 250°C, dropped to 150°C after modification with TEPA/AIFA mixture due to dehydration of the carboxylic acid and also degradation of the sulfonic acid groups 41,52 . Moreover, not in the RES thermogram, but a mass loss between 300–425°C is observed in the thermogram of MRES as a result of the degradation of the TEPA groups.…”

“…When the FTIR spectra of poly(AMPS‐co‐MA‐co‐DVB) (Res) is examined (Figure 2), characteristic bands of the MA, at 1859, 1773, and 1710 cm −1 belonging ─C─O─C─ of the anhydride and C═O of the carbonyl groups, respectively, 49,50 and characteristic bands of the AMPS, at 1645 and 1554 cm −1 belonging amide I and amide II, are appeared. In addition, the bands of the sulfonic acid groups (O═S═O and ─SO 3 H) of AMPS shown in the red circle 51–53 . After modification of the Res with TEPA/AIFA mixture, the changes in the chemical structure of Res are apparent in the FTIR spectra of the MRes.…”

“…RR‐120 dye molecules are negatively charge in aqueous solution due to sulphonate groups (─SO 3− ). The high removal of the RR‐120 at low pH results from the electrostatic interaction of these opposite charges 51,52,60 . The reduction in removal of RR‐120 between pH 2 and 6 can be attributed to the decreasing protonation of the amine groups because of decreasing in (H + ) concentration with increasing pH.…”

This study reports the synthesis and characterization of a new amphoteric resin, which can be used for the removal of both cationic, methylene blue (MB) and anionic dyes, reactive red‐120 (RR‐120). The amphoteric resin was characterized by ATR‐FTIR, SEM–EDX, TGA/DTA, DLS, BET analysis and also its surface pHpzc was determined. The prepared resin has micro porous structure and its particle size was at the nano level. The prepared amphoteric resin showed high removal affinity for MB in both acidic and basic medium, while for RR‐120 high removal affinity in acidic medium. Moreover, it was observed that the amphoteric resin has exhibited almost 100% dye removal up to 600 ppm for MB and up to 300 ppm for RR‐120, respectively. The adsorption behavior of both dyes on the amphoteric resin is in agreement with the Langmuir isotherm and the pseudo‐second order kinetic model and also electrostatic interaction is dominant in adsorption. Its capacity was slightly low for the MB than that of the commercial activated carbon, but higher for the RR‐120. Furthermore, it was observed that the amphoteric resin almost did not lose its high removal efficiency in the concentrated matrix environment for both dyes. After five repeated adsorption–desorption cycles, the high removal efficiency of the resin for the MB (almost 100%) unchanged, but for the RR‐120 decreased to 83%.

“…Methylene blue and basic violet 16 dyes were removed from an aqueous solution using sulfonated poly(ether ether ketone) (sPEEK) [ 40 ]. Kinetic experiments revealed that in the case of both dyes, data were well-fitted by the pseudo-second-order kinetic model, whereas the required times to achieve equilibrium were determined as 40 and 20 min for methylene blue and basic violet 16, respectively.…”

Even in the first quarter of the XXI century, the presence of organic dyes in wastewaters was a normal occurrence in a series of countries. As these compounds are toxic, their removal from these waters is a necessity. Among the separation technologies, adsorption processing appeared as one of the most widely used to reach this goal. The present work reviewed the most recent approaches (first half of the 2021 year) regarding the use of a variety of adsorbents in the removal of a variety of organic dyes of different natures.

Even in the first quarter of XXI century, the presence of organic dyes in wastewaters is a normal occurrence in a series of countries, and being these compounds toxics, their removal from these waters is of a necessity. Among the separation technologies, adsorption processing appeared as one of the most widely used to reach this goal. The present work reviewed the most recent approaches (first half of 2021 year) about the use of a variety of adsorbents on the removal of, also, a variety of organic dyes of different nature.
