Title:
DIATOMITE-LOADED BIOGENIC IRON-MANGANESE OXIDE MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/222392
Kind Code:
A1
Abstract:
A diatomite-loaded biogenic iron-manganese oxide material, a preparation method therefor, and an application thereof. The preparation method comprises: inoculating a strain into a culture medium containing divalent iron, divalent manganese, and diatomite to obtain a diatomite-loaded biogenic iron-manganese oxide material. The strain is a strain capable of converting the divalent iron and the divalent manganese into an iron-manganese oxide. According to the present invention, the diatomite is used as a carrier, the divalent iron and the divalent manganese are closely adsorbed on the diatomite in the form of an iron-manganese oxide under the action of the strain, and finally, the diatomite-loaded biogenic iron-manganese oxide material can be applied to remediation of arsenic-contaminated soil.
