Title:
MAGNESIUM-BASED FERROUS SULFIDE COMPOSITE NANOMATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/200871
Kind Code:
A1
Abstract:
Disclosed are a magnesium-based ferrous sulfide composite nanomaterial, a preparation method therefor and the use thereof. The preparation method is: uniformly dispersing a magnesium-based material powder into water to obtain a magnesium-based material suspension, wherein the magnesium-based material refers to at least one of magnesium oxide and magnesium hydroxide; and then adding an aqueous ferrite solution to the resulting magnesium-based material suspension, and after uniformly mixing, adding dropwise an aqueous sodium sulfide solution for reacting so as to obtain ferrous sulfide, and standing after the reaction is completed to obtain a magnesium-based ferrous sulfide composite nanomaterial. The agglomeration of ferrous sulfide particles is inhibited by loading a ferrous sulfide nanomaterial onto the surface of magnesium-based material particles to ensure the reaction activity thereof; the active surface of the magnesium-based material can efficiently adsorb a heavy metal, and improve the utilization rate of the ferrous sulfide nanomaterial. At the same time, a weak alkaline material formed by the magnesium-based material is conducive to the stable presence of the ferrous sulfide nanomaterial, so that the composite material does not easily deteriorate and is easy to preserve.
