Synthesis and adsorption investigation of hydrogel/zinc nanooxide/carbondot composite for removal of environmental pollutants

In recent years, the use of hydrogels has been considered due to high water absorption to remove dyes.By modifying the surface and using other absorbent materials, the possibility of dye absorptionincreases. In this study, we intend to investigate pollutant absorption by hydrogel and its removal bycarbon quantum dots in the presence of UV light and ambient light. For this purpose, UV-Visabsorption spectra of rhodamine B dye in different states have been investigated. The experimentalresults showed that the dye absorption capacity was the highest in rhodamine B/hydrogel/CDs/ZnOcomposite under UV light, and the reason for that was significant cross-linking by carbon dots in thehydrogel.
