| titleOfInvention | A kind of adsorption material of pyrrole copolymer grafted porous graphene and preparation method thereof |
| abstract | The invention relates to the technical field of sewage treatment, and discloses an adsorption material of pyrrole copolymer grafted porous graphene. Under the action of polystyrene microspheres, the pore structure of graphene oxide is improved, the specific surface area is increased, and the In the mixed acid, the porous graphene is oxidized to obtain graphene oxide rich in carboxyl groups. After the modification treatment of thionyl chloride, a large number of acyl chloride groups are introduced into the surface. Under the action of a catalyst, pyrrole, 3-chloropropylamine hydrochloride The reaction generates 1-(2-aminoethyl) pyrrolidine, increases the number of amino groups on the pyrrole monomer, and under the oxidation of FeCl 3 , part of 1-(2-aminoethyl) pyrrolidine, pyrrole and the group with acid chloride The carboxylated graphene forms amide bonds through electrophilic substitution reaction to obtain pyrrole copolymer-grafted porous graphene, which greatly improves the adsorption performance and adsorbs a large amount of Cr 6+ ions. Under strong acid, pyrrole copolymer-grafted porous graphene The amino group will give a lone pair of electrons, and Cr 6+ gains electrons to reduce to less toxic Cr 3+ . |
