| titleOfInvention | A kind of rapid separation and enrichment detection method of formaldehyde in milk and milk products |
| abstract | A method for rapid separation, enrichment and detection of formaldehyde in milk and milk products, comprising the following steps: preparing a standard solution of formaldehyde and a standard solution of an analyte; preparing an MBTH receiving solution; using trisodium citrate to reduce chloroauric acid solution to prepare AuNPs; The sample to be tested and the standard solution pass through the thermal purging separation and enrichment device to make the formaldehyde catalyzed reaction into formaldehyde and then separated from the matrix, which is absorbed and enriched by the receiving liquid in the trapping tube; the receiving liquid in the trapping tube is taken out; After adding the ferric ammonium sulfate solution, mix it with AuNPs and put it into the cuvette for SERS detection; draw the peak area-formaldehyde content standard curve at the Raman shift of 1275cm -1 ; take the same volume of sample and separate and enrich it by thermal purging In the device, the peak area at the 1275cm -1 Raman shift place is read after the treatment, and the control peak area-formaldehyde content standard curve obtains the formaldehyde content in the sample. The method can realize rapid and highly sensitive real-time detection on site. |
