| titleOfInvention | A kind of extraction coating, solid phase microextraction probe and preparation method and application thereof |
| abstract | The invention relates to an extraction coating, a solid-phase microextraction probe and a preparation method and application thereof. The main body of the extraction coating is a cross-linked polyvinylpyrrolidone material. The cross-linked polyvinylpyrrolidone material is activated by water absorption and swelling to realize the efficient extraction of strong polar compounds in the aqueous matrix. good reproducibility. In addition, the preparation method provided by the present invention utilizes the biocompatible polymer material to realize the assembly and coating of the cross-linked polyvinylpyrrolidone particles, the preparation steps are simple and fast, and the preparation cost is low. The prepared solid-phase microextraction probe is strong and durable, and ensures that the extraction coating does not incorporate too many other substances, so that the extraction and enrichment effect of the extraction coating can directly reflect the extraction and enrichment performance of such materials. |
