Synthesis of rhodamine modified carbon quantum dots and application of ratiometric fluorescence detection for Cu2+ and triple-mode detection for 2,4-dichlorophenoxyacetic acid
{{output}}
Background: 2,4-Dichlorophenoxyacetic acid (2,4-D) is a widely used herbicide whose environmental residues pose threats to ecology and health. Copper ions (Cu2+), as common heavy metal pollutants, can exhibit synergistic toxicity... ...
