“…Besides, the negative values of the thermodynamic parameters exhibited that the adsorption on the PAm-SO3-N5 is an exothermic process with the good capability to remove Calmagite from water samples. The findings are consistent with those of previous research (El Khomri et al, 2020;Hassan et al, 2020;Sarabadan et al, 2019;Tanhaei et al, 2015, Babamoradi et al 2021, Babamoradi et al 2022.…”

In this study, pentaazatetraethylene modified sulfonated polyacrylamide (PAm-SO3-N5) was synthesized and used as a novel efficient adsorbent to remove Calmagite from aqueous media. To this end, a central composite design (CCD) was applied to reduce the number of reaction variables (i.e., adsorbent concentration, temperature, initial concentration, and pH) on Calmagite removal.The results showed that calmagite was entirely adsorbed by the PAm-SO3-N5 within 30 min. In addition, a pseudo-second-order (PSO) model was prepared as the optimum formula to fit the kinetics information. The modeling results revealed that film diffusion and adsorption are ratelimiting stages to remove the dyes. Using a Langmuir isotherm to fit the equilibrium data, the highest equilibrium adsorption was calculated to be 1,732.5 mg/g. In the present study, the ΔH value indicates that the adsorption is of chemical type. Also, the negative sign of ΔS° shows that PAm-SO3-N5 removes Calmagite during a relatively stable process with randomness in the system.The increase in ΔG° values with increasing temperature indicates a descending trend in the feasibility degree of Calmagite adsorption. Eventually, recycling the adsorbent for 7 cycles to adsorb calmagite dye showed no remarkable activity loss.

“…Nanocomposites (NCs) are composite materials containing at least one nanoscale component. [19][20][21][22][23][24][25] Nanocomposites, specically those composed of organic polymers and inorganic llers, have garnered signicant interest in the academic and industrial sectors. These nanocomposites involve the integration of one or more organic polymer matrices with one or more nanollers, which may belong to either the organic or inorganic category.…”

The study focuses on the synthesis and characterization of a new mesoporous polysulfonamide stabilizer using condensation polymerization and the nanocasting technique. The resulting material, PGTSA, was modified with copper ions and used as a nanocatalyst in the reaction of benzaldehydes, 1H‐tetrazole‐5‐amine, and malononitrile. The performance of the mesoporous PGTSA/Cu (II) was compared with non‐porous PGTSA/Cu (II), highlighting the significance of support porosity in catalytic activity and loading of copper species. Based on the analysis of the ICP and catalytic performance, it was observed that mesoporous PGTSA/Cu (II) exhibited a higher level of catalytic activity compared to PGTSA/Fe3O4/Cu (II) and non‐porous PGTSA/Cu (II). Also, the catalytic activity of the aryl aldehyde was significantly influenced by its electrical characteristics. The recovery and reusability of the PGTSA/Cu (II) catalyst are noteworthy aspects, highlighting the practicality and sustainability of the catalytic system. The amount of copper in fresh catalyst and the recycled catalyst after six times recycling is 1.57% and 1.52%, respectively. Therefore, ICP‐OEIS analysis indicated that copper leaching of this catalyst is very low. The procedure offered high product yields, easy recovery of the nanocatalyst, remarkable reusability, short reaction times, and compatibility with various substrates.
