| abstract |
The invention discloses a preparation method of a sewage treatment catalyst, which comprises the steps of preparing a nano ferroferric oxide supported carbon quantum dot, preparing an epichlorohydrin modified nano ferroferric oxide supported carbon quantum dot, preparing a methylene blue modified nano ferroferric oxide supported carbon quantum dot, carrying out ion exchange with ammonium persulfate and the like. The invention also discloses the sewage treatment catalyst prepared by the preparation method of the sewage treatment catalyst. The sewage treatment catalyst disclosed by the invention is lower in price, more stable in effective performance, higher in photocatalytic efficiency, wider in visible light response range and more remarkable in sewage treatment effect. |
