Embodiment 1
[0028] This example is used to illustrate the method of using carboxyl quantum dots to detect Pd in simulated high-level waste liquid.
[0029] 1. Establishment of working curve
[0030] Prepare a standard solution with a concentration of 0.002g / L Pd; take several 10 μL carboxy quantum dots (quantum dot concentration is 0.25 μmol / L), and add 100 μL of citric acid-sodium citrate buffer solution with pH=3 respectively; add different volumes of For the standard solution of 0.002g / L Pd, dilute to 250μL with 0.001mol / L nitric acid; after 15min, measure the fluorescence intensity respectively.
[0031] From figure 1 From the above, the higher the concentration of Pd, the lower the fluorescence intensity of the carboxyl quantum dots, that is, the greater the degree of quenching.
[0032] The test results show that when the concentration of Pd is in the range of 0.04-0.96mg / L, and the concentration of carboxyl quantum dots in the measurement system is 10nmol / L, the logarithmic val...
Embodiment 2
[0047] 1. Establishment of working curve
[0048] Prepare a standard solution with a concentration of 0.01g / L Pd;
[0049]Take 10 μL of amino quantum dots (the concentration of quantum dots is 0.25 μmol / L), add 100 μL of citric acid-sodium citrate buffer solution with pH=3, and then add different volumes of 0.01 g / L Pd standard solution, and use 0.001 mol / L Dilute to 250 μL of nitric acid. After 15 min, the fluorescence intensity was detected respectively.
[0050] From image 3 From the above, the higher the concentration of Pd, the lower the fluorescence intensity of amino quantum dots, that is, the greater the degree of quenching.
[0051] The test results showed that when the concentration of Pd was in the range of 0.2-1.2mg / L, and the concentration of carboxyl quantum dots in the measurement system was 10nmol / L, the measured fluorescence intensity F of the quantum dots was linearly related to the concentration c of Pd.
[0052] The working curve of the amino quantum d...
