| titleOfInvention | Mercury adsorbent and preparation method thereof |
| abstract | The invention discloses a mercury adsorbent and a preparation method thereof, ZIF-67 and polyacrylic acid are subjected to ultrasonic treatment in N, N-dimethylformamide to be completely dispersed, then ferric salt, manganese salt, sodium selenate and urea are sequentially dissolved in the solution under the ultrasonic condition to be subjected to ultrasonic treatment until the system is uniformly dispersed, the dispersion liquid is subjected to hydrothermal reaction at 120-200 ℃, the product A is filtered, washed and dried to obtain a product A, the product A is dispersed in DMF, N-dicyclohexylcarbodiimide and polyacrylamide solution are added into the product A, and after the ultrasonic dispersion, stirring reaction is carried out at room temperature to obtain the adsorption material. The magnetic adsorption material prepared by the invention has the advantages of high selectivity, large adsorption capacity, environmental protection, good dispersibility, good adsorption effect on mercury and recycling. |
