Abstract
- [Display omitted] • Using a non-toxic process to prepare biomass blue light emitting carbon quantum dots. • A new fluorescence cellulose hydrogel material with NCDs as core was synthesized. • The blue light emission of the fluorescence cellulose hydrogel can be applied to detect and absorb of heavy metal ions. • Providing an idea for construction of new hydrogel materials. To combat the contaminating effects of heavy-metal ions on water resources, we prepared blue photonitrogen-doped carbon quantum dots (NCDs) from Salix psammophila (SP) as a raw material, doped them into a microcrystalline cellulose hydrogel, and successfully created a composite hydrogel (NCDs-SP-MCC-gels) for concurrent fluorescence detection and Fe3+ adsorption. The NCDs-SP-MCC-gels was examined for their shape, chemical composition, fluorescence characteristics, and adsorption behaviors. Results demonstrated that the NCDs-SP-MCC-gels displayed a broad linear range of Fe3+ fluorescence response (200–1000 mg/L; detection limit = 3.90583 mg/L) and a high adsorption capacity for Fe3+ (610 mg/g). The adsorption data fitted the Langmuir and pseudo-second-order models well. Further research was conducted on Fe3+ detection and adsorption onto the NCDs-SP-MCC-gels. This study proposes a green and sustainable way to create a material for the detection and absorption of heavy-metal ions. [ABSTRACT FROM AUTHOR]
