Abstract

The synthesized quantum dots have high solubility and stability in water and have great tendency to copper ion. This detector is based on the fluorescence quenching of cadmium sulfide functionalized quantum dots. Factors affecting on the extraction efficiency and ions fluorescence quenching were evaluated which included the amount of ionic liquid, the amount of methanol, the time of extraction, the time of centrifuge, the amount of quantum dots and pH of buffer.
