| description | The invention discloses a heavy metal passivator for reducing the bio-availability of cadmium in soil. The heavy metal passivator is prepared by mixing the following components in percentage by weight: 70 to 90 percent of biochar and 10 to 30 percent of modified sodium alginate. The heavy metal passivator disclosed by the invention not only has a function of passivating the heavy metal in the soil in situ, but also is capable of improving the soil structure and increasing the soil porosity, the pH (Potential of Hydrogen) of the soil is increased to a larger extent, and the function of repairing acidified soil is also obtained. |
