Abstract

With the scarcity of drinking water resources, the water purification and desalination increasingly receive attentions. Industrial and pharmaceutical contaminants always threaten water resources. One of the methods for water recreation is the use of ion exchange resins, which has already appeared very successful. In this regard, and in order to improve the existing methods, the main purpose of this study was to remove water cartons as an environmental pollutant from aquatic environments. For this purpose, ion exchange resins have been used as adsorbents. In this research, polystyrene was synthesized by anionic polymerization method as well as magnetic iron nanoparticles and polystyrene resin was sulfonated. Magnetic iron nanoparticles were detected by X-ray diffraction analysis. Raw polystyrene was detected and sulfonation was confirmed by infrared spectroscopy, X-ray brush, EDX elemental analysis and electron microscopy. In order to investigate possible changes in the structure of polystyrene after sulfonation, the XRD spectrum of sulfonated resin was also recorded. The result of the hair is the preservation of the structure of polystyrene after the sulfonation process. Then EDX test was performed for 2 resins. The results showed that the percentage of sulfur in the samples increased from 0.02% in the raw resin to 0.34% in the sulfonated sample. The results of electron microscopy showed that the raw resin has a spherical morphology with a size in the range of 94 to 128 nm, while the sulfated polystyrene resin has a porous morphology. It is worth mentioning that the sulfonated resin has porosity in the range of 169 and 248 nm and the average particle size is 212 nm. X-ray diffraction analysis showed that the sample had long and strong peaks. Finally, the sulfonated resin was used to remove salt from the water using a synthetic calcium carbonate solution. The changes of the pH of the solution by removing salt from the solution was recorded by the mentioned resin. The
