In this study, (hydroxypropylmethacrylate-co-ethyleneglycol dimethacrylate-co-glycidylmetharylate) terpolymer resin functionalized with sulfonic acid groups was prepared and used as cation exchange resin for removal of two different disperse dyes (i.e., Direct Red R [DR-R] and Disperse Violet 28 [DV-28]) from aqueous solution. The properties of the adsorbent were determined using Fourier transform infrared, dynamic light scattering, scanning electron microscopy, and Brunauer, Emmett, and Teller methods. The maximum adsorption capacity of the resin for the DR-R and DV-28 was found to be 86.1 and 179.6 mg/g, respectively. Desorption study was realized to evaluate the reusability of the resin and the percent desorption from the resin for DR-R and DV-28 dyes was found to be approximately 89.4% and 91.7%, respectively. The experimental data were evaluated using different kinetics and isotherm models. These results show that the experimental data could be designated with the second-order kinetic model and both Langmuir and Temkin isotherm models. Finally, the presented resin was able to remove large amounts of organic pollutants in a short process time with a low amount of adsorbent. Thus, it was shown that the prepared resin has high potential for use as an effective and sustainable adsorbent for the treatment of industrial wastewater. POLYM. ENG. SCI., 2019.
