| titleOfInvention | Magnetic Fe in the environment3O4Circulating enrichment device for separating and extracting nano particles and detection method thereof |
| abstract | The invention provides magnetic Fe in environment 3 O 4 The invention relates to a circulation enrichment device and a detection method for separating and extracting nano particles, wherein a 3D printing technology is adopted, a magnetic nano particle circulation enrichment device comprising an enrichment component is designed, potassium hydroxide is adopted to be dissolved under a heating condition to completely digest and disperse a PM2.5 sample collected by a quartz filter membrane, and after the dispersed sample solution is extracted by a circulation enrichment device, a low-concentration acetic acid solution is adopted to purify the sample solution to obtain Fe with simple matrix 3 O 4 The magnetic nano particles, the sample treatment method and the circulating enrichment device are combined to completely digest and disperse the PM2.5 sample collected by the quartz filter membrane as much as possible and to carry out magnetic Fe in the collected PM2.5 sample 3 O 4 The method has the advantages of simple operation and high sample recovery rate, and can be applied to extraction of environmental samples from various sources. |
