Case Study

Extraction of Lead from Soil by Washing with Sodium Ethylenediamine Disuccinate

Szanto, Maria, et al. ProEnvironment Promediu, 2012, 5(11).

Soil washing refers to the removal of metals from soil using water and various reagents (acids, oxidants, chelating agents, etc.). EDDS ([S,S - ethylenediamine disuccinic acid]) is one of the most studied chelating agents due to its ability to form biodegradable complexes. In this work, lead was extracted from soil by washing with trisodium ethylenediamine disuccinate (Na3EDDS), and the optimal conditions for the extraction process were studied.
Optimization of Na3EDDS washing process
The experimental soil samples were heavily contaminated with Cu, Zn, Pb, and Cd. Soil samples were washed with NaEDDS for 2, 4, 6, and 8 h, with Na3EDDS solution concentrations of 0.4, 0.5, and 0.6 [%], respectively. Sample mixing was performed using a stirrer with a platform and orbital oscillation-rotation motion at a stirring speed of 200 times/min. Lead was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES).
The optimal flushing parameters were determined: 8 h of soil flushing with 0.6% Na3EDDS gave a maximum yield of 85.54%.

Sodium Ethylenediamine Disuccinate Used for Chemical Leaching to Remove Toxic Elements from Mineral Particles in Contaminated Soil

ŠTYRIAKOVÁ, IVETA, et al. Mineralia Slovaca, 2019, 51, 2.

Researchers tested four experiments to extract toxic elements from contaminated soil using both chemical (CHL) and biological (BL) treatments. Chelating agents employed included Ethylenediaminetetraacetic acid disodium salt dihydrate (Na2EDTA, ch1), Ethylenediamine-N,N'-disuccinic acid trisodium salt (Na3EDDS, ch2), and indigenous heterotrophic bacteria.
Key Findings
The results from the four leaching tests indicated that Cu(II), Zn(II), and Pb(II) were successfully removed through chemical leaching. The combination of biological and chemical leaching enhanced the extraction of As(III)/(V), allowing these mobile forms to be leached from the soil. Additionally, this combined approach required lower quantities of chelants, thus reducing the costs associated with soil treatment. Based on the findings, a straightforward bioremediation method was developed and tested with successful outcomes:
· Chemical leaching with Na2EDTA aimed at removing Cu(II), Zn(II), and Pb(II).
· Chemical leaching with Na3EDDS designed to eliminate non-biodegradable chelants and other toxic elements and heavy metals.
· Bioleaching of the contaminated soil utilizing a less concentrated chelant in the leaching medium enriched with nutrients to maximize the removal of mobile As(III)/(V).
These three soil decontamination steps should be implemented in heaps, where the contaminated soil would be treated with the leaching media. The resulting leachates would be collected in basins to facilitate the recycling of the leaching media and the concentration of heavy metals.
