Abstract

The invention discloses a transition metal phosphide modified nano-iron composite material, a preparation method and application thereof. The preparation method of the composite material comprises the following steps: uniformly mixing transition metal phosphide and zero-valent iron according to a mass ratio of 1:(5-1000); and under an inert or reducing atmosphere, carrying out ball milling on the obtained mixture to obtain the transition metal phosphide modified nano-iron composite material. According to the invention, metal phosphide is loaded to the surface of zero-valent iron, and the metal phosphide can catalyze reduction of organic chlorine chemicals, so that the reductive dechlorination performance of the nano-iron material is greatly improved, and the nano-iron composite material can be used for treating and repairing soil and underground water polluted by organic chlorinated hydrocarbon.

Description

technical field [0001] The invention relates to the technical field of environmental restoration and material preparation, in particular to a transition metal phosphide-modified nano-iron composite material and a preparation method and application thereof. Background technique [0002] Organochlorine compounds such as trichlorethylene are colorless, volatile and insoluble liquids. Organochlorine compounds are widely used industrial raw materials, mainly used as extractants for fats, spices and paraffins, solvents for various natural rubber, plastics and asphalt, petroleum refining, printing inks, binder manufacturing, and refrigerator refrigerants and clothes Dry cleaning agent and so on. Organochlorine compounds have obvious biological toxicity, and skin contact can cause skin rash, and long-term exposure can cause liver function damage and cancer. [0003] Since organochlorine is a commonly used solvent, it can enter the environment through various channels. It is one of...
