Preparation of Kiwifruit Biomass Carbon Dots by Microwave Method and Application of Fe3+ Detection in Honeysuckle
In order to establish a rapid detection method for Fe3+, the kiwifruit biomass carbon dots (CDs) were prepared by microwave method with kiwifruit juice as carbon source and ethylenediamine as surface modifier. The CDs were rich in -OH, -NH and C-O groups, had an average particle size about 2.5 nm, w...

| description | In order to establish a rapid detection method for Fe3+, the kiwifruit biomass carbon dots (CDs) were prepared by microwave method with kiwifruit juice as carbon source and ethylenediamine as surface modifier. The CDs were rich in -OH, -NH and C-O groups, had an average particle size about 2.5 nm, which were soluble in water and stable. The CDs emitted blue fluorescence under 365 nm ultraviolet light. A new and rapid detection method for Fe3+ was established with the CDs based on the fluorescence quenching effect of Fe3+. When the addition amount of Fe3+ from 0.2 to 10 μmol/L, the fluorescent intensity (F/F0) of CDs decreased linearly with the increase of Fe3+(R2=0.9934), and the limit of detection (S/N=3) was 0.12 μmol/L. This detection method was applied to the determination of Fe3+ content and the recovery was 98.82%～103.20% , RSD was between 1.67% and 2.05%. The operation of this detection method was simple, rapid and strong selective. |
