Title:
CARBON-LOADED NANO ZERO-VALENT IRON MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/129137
Kind Code:
A1
Abstract:
A method for preparing a carbon-loaded nano zero-valent iron material. The method comprises: firstly, preparing an MIL-88A type iron MOF; roasting an MOF precursor in a reducing atmosphere (H2/Ar mixed atmosphere); and then preparing a carbon-loaded nano zero-valent iron material the morphology of which still being shuttle-shaped. The present invention also relates to a carbon-loaded nano zero-valent iron material obtained by the described method and an application of a carbon-loaded nanoscale zero-valent iron material in the remediation of chromium-contaminated soil. The preparation method is simple, and an in-situ reduction mode can ensure the high dispersion of zero-valent iron, thereby enabling the capability thereof in reducing and fixing chromium is significantly improved relative to pure zero-valent iron; in addition, the method may be widely applied to the field of heavy metal-contaminated soil remediation.
