| titleOfInvention | Method for reinforcing coupling and passivating nano zero-valent iron system by iron reducing bacteria |
| abstract | The invention relates to a method for coupling and passivating a nano zero-valent iron system by using reinforced iron reducing bacteria, which specifically comprises the following steps: step 1, completing preparation of the graphene oxide loaded nano zero-valent iron, wherein: preparing graphene oxide by adopting a Hummers method, adding 200mg of prepared graphene oxide into a 250mL three-neck flask, dissolving 0.496g of ferrous sulfate heptahydrate into a mixed solution of 60mL of water and 20mL of ethanol, adding the mixed solution into the three-neck flask, and carrying out ultrasonic treatment on the mixed solution for 30min at 50kHz on an ultrasonic instrument; 2, degrading 4-chlorophenol by using graphene oxide loaded nano zero-valent iron; step 3, performing artificial culture of Shewanella; step 4, finishing the degradation of 4-chlorophenol by reducing and passivating nano zero-valent iron by graphene oxide mediated Shewanella; the graphene oxide loaded passivated nano zero-valent iron coupled Shewanella is used for strengthening a coupling system, reducing the formation of a passivation layer, improving the reaction activity of the system and overcoming the defect that nano zero-valent iron is easy to inactivate through the coupling effect of iron reducing bacteria Shewanella and materials. |
