| titleOfInvention | A kind of soil heavy metal passivant and preparation method and the passivating method to Cadmium in Soil |
| abstract | The invention belongs to remediation of heavy metal-contaminated soil fields, and in particular to a kind of soil heavy metal passivant and preparation method and the passivating method to Cadmium in Soil.Soil heavy metal passivant of the present invention includes 30 ~ 50 parts of modified alkaline mineral, 10 ~ 15 parts of decomposed agriculture and forestry organic waste material, 1 ~ 10 part of soil conditioner, 1 ~ 5 part of pH sensitivity gel, 1 ~ 5 part of ardealite, 0.1 ~ 5 part of graphene by weight.Soil heavy metal passivant of the present invention has stronger absorption chelating effect, can heavy metal cadmium in effective fixing soil, block effective cadmium to enter in crops body；It can be regulated and controled according to soil pH, improve the utilization rate and long-time stability of soil heavy metal passivant；The soil conditioner of addition can improve soil environment simultaneously, increase soil fertility.The passivator of the invention urgent need that preferably to meet that current China's heavy-metal contaminated soil reparation is strong to stability, without secondary pollution, effect is lasting stable. |
