| titleOfInvention | Method for determining cadmium in water sample based on fluorescein-PAN fluorescence method |
| abstract | The invention belongs to the technical field of cadmium determination, and discloses a method for determining cadmium in a water sample based on a fluorescein-PAN fluorescence method, which adopts 0.70mL of 0.75 ammonia water-ammonium chloride buffer solution with the dosage and 9.68 × 10 PAN concentration ‑5 mol·L ‑1 The concentration of fluorescein is 1.0 × 10 ‑5 mol·L ‑1 (ii) a The reaction time was 15 min. The method is simple to operate, sensitive, quick, economical and practical, can be used for actual detection, and is consistent with the result of the national standard graphite furnace atomic method (t test). The invention mainly refers to that in a buffer solution medium, PAN and FR can generate energy transfer to enable FR to generate fluorescence quenching, when Cd (II) is added into a system, the quenching degree of FR is enhanced, and a novel method for detecting cadmium in an environmental water sample is established by utilizing the property. Provides a certain experimental basis and technical method for detecting heavy metals in the environment. |
