| titleOfInvention | A kind of preparation method and application of iron sulphur multiphase-fenton fenton catalyst |
| abstract | The present invention relates to a kind of preparation method and application of iron sulphur multiphase-fenton fenton catalyst, comprise the following steps：Dispersant is added into ferrous solution, and is stirred.Sulfohydrate, sulfide solution are slowly poured into above-mentioned solution successively, maintain pH value of solution to stir 10 ~ 20min 5.0 ~ 5.5.It will be slowly added into sulfite solution into solution again, and maintain pH value to stir 5 ~ 10 min, obtain precursor sol 5.0 ~ 5.5.Precursor colloidal sol is transferred in sealed glass jars, lucifuge constant temperature（25℃）Aging reaction, it is final catalyst to obtain black precipitate.Wastewater pH is adjusted to 7.0 ~ 11.0, adds the multiphase-fenton fenton catalyst of hydrogen peroxide/persulfate mixed liquor and synthesis into waste water, the min of the min of stirring reaction 10 ~ 120, that is, completes the degraded to organic pollutants.Iron sulphur multiphase-fenton fenton catalyst produced by the present invention, preparation process is simple, mild condition, and applicable pH range is high during use, good to advanced treatment of industrial waste water effect. |
