Pretreatment of solid food samples based on ionic liquids |
| abstract |
The present invention provides a method for the pretreatment of solid food samples based on ionic liquid. post-filtering. Compared with wet digestion, the pretreatment method established in the present invention can shorten the pretreatment time by 36 to 48 times, and reduce the amount of acid solution by 12 to 20 times, thereby providing a method for detection and analysis of heavy metal ions in food solid samples. Green, safe and fast pretreatment technology. |
