Synthesize Fluorescent Nanomaterials from Kiwi to Detect Metal Ions

Source: Zhengzhou Fruit Research Institute

The team of fruit quality safety control technical is committed to developing multifunctional nanomaterials from biomass carbon sources. This team used kiwi as biomass carbon sources to synthesize a new fluorescent nanomaterials (KF-CDs) that have the great potential in the sensitive detected of Fe3+. From the fluorescence interference experiment, it was obviously quenched by Fe3+ within seconds, and have a good linear relationship between 1-33.8 μmol/L, the linear equation was y=0.9546+0.0689x (R=0.996), and the detection limit was 0.097 μmol/L. The WHO stipulated that Fe3+ in drinking water should not exceed 0.3mg/L (∼5.36 μmol/L).

This work was supported by the Agricultural Science and Technology Innovation Program (Grant CAAS-ASTIP-2019-ZFRI-10) and by the Central Public-interest Scientific Institution Basal Research Fund (No.1610192020107).
