| titleOfInvention | Heavy metal scavenger and preparation method and application thereof |
| abstract | The invention relates to the technical field of environmental pollution treatment, in particular to a heavy metal scavenger and a preparation method and application thereof, wherein the heavy metal scavenger comprises the following components in parts by weight: 4-9 parts of chelating agent, 2-5 parts of passivating agent, 1-3 parts of ion exchanger, 0.5-2.5 parts of high molecular water-absorbing material, 0.5-5.5 parts of magnetic powder and 65.5-85.5 parts of adhesive. The heavy metal scavenger has good toughness, strength and water absorption, excellent recyclability and high efficiency, can effectively scavenge heavy metal ions in soil, water and/or sludge, can be recovered after being saturated for a period of time, can effectively reduce the content of heavy metals in a treated object, contains nutrient elements such as calcium, magnesium, nitrogen, phosphorus and the like which have promotion effects on the growth of crops, and does not influence the normal cultivation of agricultural lands. |
