The present invention relates to a new room temperature synthesis method of stable iron ions nanoparticles in the air, and more particularly to a method for preparing nano-sized valent iron (NZVI) having a thin outer oxide layer and the environmental pollutants using the prepared nano-sized valent iron. It relates to a treatment method.n n n According to the present invention, air dried NZVI is very efficient at removing contaminants such as arsenic, and the method of drying NZVI at room temperature according to the present invention is simple, cost-effective, environmentally friendly, and 10 months. This is the method that can be stabilized in the air. |
