Abstract
The present invention relates to the field of environmental pollution remediation technology, in particular to a nanocomposite preparation and a method for making the same and use thereof. The nanocomposite preparation provided herein includes a nanomaterial and an extracellular polymeric substance (EPS) solution of a microorganism, where the nanomaterial is graphene oxide (GO) or multi-walled carbon nanotubes (CNT); and the microorganism isHPD-2, deposited in China General Microbiological Culture Collection (CGMCC) Center, with a deposition number of CGMCC No. 2568. The nanomaterial and EPS system in the present disclosure may improve the bioeffectiveness of Polycyclic Aromatic Hydrocarbons (PAHs) in soil and thus the degradation of PAHs compared to a single system. The synergistic effect between the nanomaterial and the EPS of the degrading bacteria significantly improves the removal of PAHs from soil and water, thus greatly reducing the remediation cycle of the PAH-contaminated soil and water.
