titleOfInvention | A method for the determination of NH4+ by using nano-silver catalyzed surface-enhanced Raman spectroscopy |
abstract | The invention discloses a method for measuring NH 4 + by using nano-silver catalyzed surface-enhanced Raman spectroscopy, which is characterized by comprising the following steps: (1) preparing a standard solution system of NH 4 + with a known concentration; (2) preparing a blank Control solution system; (3) Calculate ΔI=I‑I 0 ; (4) Make a working curve based on the concentration relationship of ΔI to NH 4 + ; (5) Prepare the sample solution to be tested, and determine its surface-enhanced Raman peak intensity as For I sample , calculate ΔI sample =I sample -I 0 ; (6) according to the working curve, calculate the concentration of NH 4 + in the tested sample. This method uses ligands to regulate the catalytic activity of nanozymes, and the method is simple, rapid and highly sensitive. |
