| titleOfInvention | Heavy metal lead-arsenic compound contaminated soil remediation agent and preparation method thereof |
| abstract | The invention discloses a heavy metal lead-arsenic compound contaminated soil remediation agent which is characterized by comprising the following raw materials in percentage by weight: 30-75% of modified carbon material and 25-70% of humic acid modified attapulgite material. The soil remediation agent can efficiently adsorb lead and arsenic in soil, and does not obviously change soil properties and farming conditions. After curing for three months, the repairing agent can reduce the content of effective lead and arsenic in soil by about 40-70%, reduce the content of arsenic and lead absorbed by sensitive crops by 44-84%, and prolong the action time by more than 3 years. Meanwhile, the material has the characteristics of low cost, simple preparation process, no secondary pollution, quick response, easy large-area popularization and the like, and can be widely applied to the remediation of the agricultural land soil which is compositely polluted by lead and arsenic. |
