| titleOfInvention | Hydrophobic metal trapping agent and preparation method thereof |
| abstract | The invention discloses a hydrophobic metal trapping agent and a preparation method thereof, wherein the method comprises the following steps: first, aminopropyl isobutyl silsesquioxane (NH) was added 2 POSS), Dicyclohexylcarbodiimide (DCC), 4-Dimethylaminopyridine (DMAP) and dichloromethane are mixed, stirred and fully dissolved to obtain a mixed solution a; then, mixing and stirring 3-mercaptopropionic acid (MPA) and absolute ethyl alcohol to fully dissolve to obtain a mixed solution b; then, slowly dripping the mixed solution a into the mixed solution b under the stirring condition, and continuing stirring for reaction after the dripping is finished to obtain a generated solution; finally, the resulting solution is purified to obtain a hydrophobic metal capture agent (MPA-POSS for short). The hydrophobic metal trapping agent can remove heavy metal pollution in a water phase without adding any flocculating agent, can realize enrichment determination of trace or trace heavy metals, has no residue in a water body, does not cause secondary pollution, and meets the requirement of environmental protection. |
