| titleOfInvention | Remove heavy metal Cr in water under weak magnetic field6+Method (2) |
| abstract | The invention relates to a method for removing heavy metal Cr in water based on a weak magnetic field 6+ Belonging to the technical field of water pollution treatment. The method mainly comprises the step of adding the graphene oxide loaded nano zero-valent iron composite material into the heavy metal Cr-containing composite material 6+ Then placing the water in a non-uniform weak magnetic field, stirring the solution, fully adsorbing the solution until the reaction is complete, and filtering by using a water system filter head to finish Cr in the water solution 6+ And (4) removing. The method has the advantages of simple preparation, high reaction activity and removal efficiency and good circulation effect, and can efficiently and quickly adsorb heavy metal Cr in the reduction wastewater in a wider pH range 6+ Overcomes the defects of large material dosage, high cost and Cr pair in the prior art 6+ The problem of slow reaction rate is solved. |
