Surface modified amorphous zero-valent iron, preparation method and application thereof

The invention belongs to the technical field of disposal of organic waste water by means of an advanced oxidation process, and particularly relates to surface modified amorphous zero-valent iron, a preparation method and an efficient disposal technique applied to organic waste water. The invention aims to prepare the surface modified amorphous zero-valent iron by combining melt-spinning method andhigh energy ball milling method in use and introducing a polyelectrolyte into a ball milling system. The dispersibility and the transfer ability of zero-valent iron particles in a water body are improved while the zero-valent iron has relatively good chemical activity in disposing organic waste water in an advanced oxidizing system. Therefore, the technical problems that a zero-valent iron material in the prior art is easy to agglomerate, low in chemical activity, high in cost and the like if being used for disposing waste water by advance oxidization are solved. 本发明属于高级氧化法处理有机废水的技术领域，具体地，涉及种表面改性的非晶零价铁、其制备方法和应用于有机废水的
