Amine functionalized poly (glycidyl methacrylate) hydrogels for Congo red adsorption
Dyes are one of the most common pollutants in wastewater due to their widespread use. Therefore, in order to protect aquatic ecosystems, dyes must be treated in situ and/or in vivo. In this study, we synthesized poly (glycidyl methacrylate) (PGMA) gels and then modified with diethylenetriamine (DETA) and tetraethylenepentamine (TEPA) containing different numbers and lengths amino groups to obtain PGMA-NH2 hydrogels and used in CR adsorption. The adsorption studies were carried out according to batch adsorption procedure. As a result of the study, the contact time was found 40 minutes and the highest adsorption capacity of 196 and 147 mg/g for PGMA-DETA and PGMA-TEPA was reached, respectively. Isotherm and kinetic experiments showed that adsorption obeys the Freundlich isotherm and pseudo-second-order equation. CR dye is an anionic indicator dye. These results showed that PGMA-NH2 hydrogels have significant potential for efficient adsorption of anionic dyes.
期刊介绍：
Journal of Environmental Engineering and Science is an international, peer-reviewed publication providing a forum for the dissemination of environmental research, encouraging interdisciplinary research collaboration to address environmental problems. It addresses all aspects of environmental engineering and applied environmental science, with the exception of noise, radiation and light.
