| titleOfInvention | Method for simultaneous elution of soil co contaminants through chemical flushing technology |
| abstract | The invention discloses a method for synchronously eluting soil composite pollutants by nchemical flushing technology with chelating surfactant. Sodium N-lauroyl ethylenediamine ntriacetate (N-LED3A) is a novel chelating surfactant, which is synthesized by introducing a nlong-chain fatty acyl group by taking an excellent chelating agent EDTA as a matrix, the nreagent is easy to biodegrade, and its molecular structure has both chelating function and nsurface activity, which is the key to realize simultaneous elution of heavy metals and organic ncontaminants in soils. N-LED3A surfactant can solubilize polycyclic aromatic hydrocarbons in nmicelle through the partitioning effect of hydrophobic groups, and the amino-carboxyl ligand non the hydrophilic chain of the micelle can chelate heavy metals, so as to achieve the effect of nsimultaneously eluting hydrophobic organic compound and heavy metal in the soil. At the same ntime, the N-LED3A surfactant in the present invention can also wash heavy metal contaminated nsoil or polycyclic aromatic hydrocarbon contaminated soil. |
