| titleOfInvention | Method for Selectively Determining Cu2+ by Fluorescent Carbon Dots Synthesized by One-Step Microwave Hydrothermal Synthesis |
| abstract | The invention discloses a method for selectively determining Cu2+ by using fluorescent carbon dots synthesized by one-step microwave hydrothermal, which is characterized by comprising the following steps: SI, preparing carbon dots; S2, separating and purifying carbon dots; S3, concentrating the carbon dot solution; S4, adjusting the pH value of the carbon dot concentrated solution to 14, taking the carbon dot solution, scanning the emission spectrum of the carbon dot solution in the range of 360-580 nm, and detecting the fluorescence intensity; S5: concentrating the solution containing metal cations to a near saturation state, pouring the concentrated solution containing metal cations into the carbon dot solution, scanning the emission spectrum of the carbon dot solution, detecting fluorescence intensity, and obviously quenching the fluorescence of the carbon dot solution, so that the solution containing metal cations contains Cu2+. The invention uses the carbon dot as a fluorescence probe. |
