| titleOfInvention | A kind of synthetic method of lanthanum-doped graphene oxide nanocomposite defluorinating agent |
| abstract | A method for synthesizing a lanthanum-doped graphene oxide nano-composite defluorinating agent belongs to the production method of the defluorinating agent. (1) using graphene oxide, hydrated lanthanum chloride and ammonia water as raw materials; (2) weighing graphene oxide, hydrated lanthanum chloride and water according to the mass ratio of 1:30:1000; (3) weighing After the good graphene oxide is mixed with water, it is ultrasonically dispersed for 2h, and then centrifuged at a speed of 3000rpm. The upper layer liquid after the centrifugation is a graphene oxide colloid; (4) the weighed hydrated lanthanum chloride is added to the above-mentioned colloid. In, after mixing, ultrasonic dispersion 30min; (5) then drip 8mol L -1 ammonia water to the system to pH 8-10; (6) then place the system in a 60 ℃ water bath and continue to stir for 1h, and age at room temperature for 24h; (7) Then filter and wash with water until the filtrate is neutral; (8) The filter residue is dried at 60° C. for 24 hours, and pulverized to obtain a lanthanum hydroxide/graphene oxide carbon-based nanocomposite defluorinating agent. Advantages: simple process, easy operation, suitable for large-scale production and application. |
