| titleOfInvention | Surface enhanced raman spectroscopy detects nitrite anions method and application thereof fast |
| abstract | The present invention relates to method and application that Surface enhanced raman spectroscopy detects nitrite anions fast.The Raman signal of nitrite anions self is very weak, SERS signal is also very weak, under acidity or weak basic condition, nitrite ion and diazonium-coupling reagent generate para-dye, the SERS signal of para-dye is strong, and the amount being measured para-dye by SERS carries out quantitative and qualitative analysis detection to nitrite anions indirectly.The present invention adopts Au/SiOn 2 as SERS base material, silica shell improves the stability strengthening particle, makes result repeatability better.This method is applicable to the Fast Measurement of the complex sample Nitrites such as food, environment, biological sample, have simple, (about 5min), selectivity are high fast, be applicable to Site Detection, be conducive to advantages such as promoting the use of. |
