Abstract:

One of the most important principles in the twenty-first century is to provide clean water, and the use and dimensions of advanced technologies in water supply are important. One of the most effective directing methods in water treatment is the adsorption method. Especially in recent years, with the re-evaluation of wastes on the agenda, instead of being left to rot, shellfish are re-evaluated by chemical or biological methods and new products are obtained. Chitin and its main derivative, chitosan, are the main products produced in this way. In order to increase the performance and efficiency of using chitosan in water treatment, it is necessary to mechanically strengthen and functionalize chitosan. In this study, it was aimed to prepare a graphene oxide (GO)-doped chitosan microcapsule modified with Fe₃O₄ nanoparticle. Chitosan-based microcapsules containing different ratios of GO@Fe₃O₄ were prepared. GO, GO@Fe₃O₄ and microcapsules (MC); Characterizations were carried out using methods such as SEM, FTIR, EDX mapping, XPS and TGA, and arsenic adsorption performance was investigated in real water samples. In line with the results obtained, it was observed that it showed a stable and high arsenic adsorption performance of 95%.
