| description | The invention discloses a preparation method of a Fenton-like catalyst, and belongs to the field of heavy metal wastewater resource utilization. The preparation method of the Fenton-like catalyst comprises the following steps: S1, putting a prepared porous calcium silicate adsorbent into heavy metal wastewater for adsorption, and when the pH value is 5-10.5, adding sulfide for primary vulcanization; and S2, collecting the primarily vulcanized porous calcium silicate adsorbent, adding the primarily vulcanized porous calcium silicate adsorbent into a sulfide solution, carrying out secondary vulcanization, filtering and separating a product, washing, and drying to obtain the Fenton-like catalyst. The method is simple in operation process and low in cost, and resource utilization of heavy metals can be realized while the heavy metal wastewater is purified.
