| titleOfInvention | A method and system for accelerating the removal of Cr(VI) in water based on the regulation of surface functional groups by zero-valent iron sulfide |
| abstract | The invention relates to a method and a system for accelerating the removal of Cr(VI) in water by zero-valent iron sulfide based on the regulation of surface functional groups. A carboxyl-containing compound is added to the wastewater system for removing Cr(VI) from zero-valent iron sulfide, and in the system The addition of hydroxyl-containing compounds accelerates the removal of Cr(VI) in water. Since the sulfide layer on the surface of zero-valent iron sulfide attracts the hydroxyl group in the solution, and the carboxyl group-containing compound in the solution has a complexation effect on Cr(VI), when the solution contains both hydroxyl group and carboxyl group, the hydroxyl group and the carboxyl group are both The presence of hydrogen bonds between the groups makes the carboxyl complexes of Cr(VI) tend to migrate to S-ZVI, which attracts hydroxyl functional groups, thereby accelerating the removal of Cr(VI) from water by zerovalent iron sulfide. The invention adopts conventional zero-valent iron sulfide and a system containing both hydroxyl compounds and carboxyl compounds to accelerate the removal of Cr(VI) in water, with simple process and low cost. |
