| Özet |
| In this study, sulfone groups carrying a hybrid hydrogel were synthesized through network-forming redox polymerization in the presence of a redox initiator pair. Through the defined one-pot polymer synthesis chemistry, the hybrid hydrogel with 2-acrylamido-2-methyl-1-propanesulfonic acid (APSA) and 2-hydroxyethylmethacrylate (HEMA) with its well-known advantages and high affinity toward cationic micro-pollutants by ion-exchange route had been synthesized. The prepared hydrogels were characterized using ATR-FTIR spectroscopy, SEM, zeta-sizer, swelling studies, and the BET method. The dye adsorption performance of the hydrogel adsorbent was determined with cationic dyes, Crystal Violet (CV), and a carcinogen dye, Congo Red (CR). The effect of various system parameters, such as contact time, adsorbent dose, ionic strength, medium pH, initial dye concentration, and temperature, was tested for the adsorption of CV and CR dyes in the hydrogels. The maximum adsorption capacity for the p(HEMA-APSA)-2 hydrogel at 25 ℃ was 306.1 and 186.9 mg/g for CV and CR, respectively. The Langmuir isotherm model is more suitable for fitting the experimental data for CV and CR adsorption. The adsorption capacity of p(HEMA-APSA)-2 hydrogel for CV and CR dyes increased by 2.1 and 2.3 fold, respectively, by increasing the temperature from 15 ℃ to 45 ℃. CV and CR adsorption were spontaneous and endothermic based on thermodynamic studies. After five repeated use cycles, p(HEMA-APSA)-2 hydrogel could be repeatedly used with high stability. A comprehensive investigation of the hydrogel adsorbent showed that it has promising potential for removing pollutants from solution. |
