▎ 摘　　要

NOVELTY - Composition comprises sulfonated graphene and amino acids. The amino acids are leucine, glutamic acid and ornithine. USE - Composition for enhancing microbial remediation efficiency of polycyclic aromatic hydrocarbon-contaminated soil (claimed). ADVANTAGE - The composition improves the microbial remediation efficiency of polycyclic aromatic hydrocarbon contaminated soil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for repairing soil using the composition, which involves mixing the aqueous solution of the composition with the soil to be repaired, where the microorganisms in the soil repair the soil under the action of the compound, and the microorganisms are indigenous microorganisms that degrade polycyclic aromatic hydrocarbons in soil.
