| titleOfInvention | Soil remediation agent capable of treating heavy metal pollution and preparation method thereof |
| abstract | The invention discloses a soil remediation agent capable of treating heavy metal pollution and a preparation method thereof, and belongs to the technical field of soil remediation. The soil remediation agent is a solid powdery soil remediation agent and comprises the following components in parts by weight: 35-65 parts of modified zeolite powder, 10-18 parts of fluorite powder, 6-13 parts of modified chitosan, 14-22 parts of potassium humate and 5-12 parts of sodium aminotriacetate; wherein, the modified zeolite powder is prepared by organically modifying zeolite powder by sodium dodecyl sulfate and acetic acid. Ball milling the above raw materials, dispersing with ethanol, filtering, oven drying, and sieving to obtain powdered soil repairing agent. According to the invention, the zeolite powder subjected to organic modification treatment by using sodium dodecyl sulfate and acetic acid is added, and the zeolite powder is compounded with fluorite powder, sodium aminotriacetate and other components, so that the effect of removing heavy metals such As Cd, Pb, As, Co and the like in soil is obvious, and the heavy metal pollution problem of soil can be effectively solved. |
