| titleOfInvention | Soil metal passivator and preparation method thereof |
| abstract | The invention provides a soil metal passivator and a preparation method thereof, and relates to the technical field of soil metal passivators. The soil metal passivator provided by the invention is a coated slow-release soil metal passivator, which comprises a core material and a coating material coated on the surface of the core material, wherein the core material is mainly made of clay minerals, phosphorus-containing materials, iron-containing materials and the like, the coating material is a polyacrylamide coating material, and through the matching of the core material and the coating material, active ingredients in the core material have long-acting slow-release performance, so that the soil metal passivator has high soil remediation efficiency and long remediation time-effect, and can continuously adjust the activity of heavy metals in forms of iron-manganese oxide binding state, organic binding state and the like, reduce the biological effectiveness of the heavy metals, and in addition, the soil metal passivator contains various nutrient elements and can provide nutrients for crops. The invention also provides a preparation method of the soil metal passivator, which is simple in process, convenient to operate and suitable for industrial production. |
