Soil washing is an effective approach to remove soil heavy metals, and the washing agent is generally regarded as one of the primary factors in the process, but there is still a lack of efficient and eco-friendly agents for this technique. Here, we showed that four plant washing agents—from water extracts of Coriaria nepalensis (CN), Clematis brevicaudata (CB), Pistacia weinmannifolia (PW), and Ricinus communis (RC)—could be feasible agents for the removal of soil lead (Pb), zinc (Zn), and… Expand
Enhancing the soil heavy metals removal efficiency by adding HPMA and PBTCA along with plant washing agents.
The addition of HPMA or PBTCA with the plant agents could improve the removal of soil heavy metals. Expand
Simultaneous Multi-metal Removal from Soil with Washing Agents of Waste, Plant and Microbial Origin

PESA is an ecological benefit eluent for remediating the farmland polluted by heavy metals, and the risk assessment based on labile fraction more easily identifies the dynamic change of heavy metal during the washing process. Expand
Compound washing remediation and response surface analysis of lead-contaminated soil in mining area by fermentation broth and saponin
A compound eluent constructed using the prepared citric acid fermentation broth and saponin displayed a good washing performance for Pb, Cu, Cr, and Cd in red soil, and the removal rates gained an improvement compared with a singleEluent. Expand
Utilization of Waste Leaves Biomass of Myrica Esculenta for the Removal of Pb (II), Cd (II) and Zn (II) Ions from Waste Waters
In the present study, we have used the waste leaves of Myrica esculenta for the removal of Pb2+, Cd2+ and Zn2+ ions from the synthetically prepared waste water. The adsorption based removal processExpand


Humic substances from sewage sludge compost as washing agent effectively remove Cu and Cd from soil.
Investigation of whether inexpensive humic substances from sewage sludge compost could effectively remove copper (Cu) and cadmium (Cd) from highly contaminated sandy clay loam (S1) and clay (S2) found that triple washing lowered the potential ecological risk of the soils and showed potential for treating soils highly contaminated with heavy metals.

Metal (Cu, Cd and Zn) removal and stabilization during multiple soil washing by saponin.
Based on the redistribution index, the most stable metal after triplicate washing was Cu in loamy sand and loam, and for silty clay contaminated with Cd, effective metal removal and its stabilization required a higher number of washings. Expand
Removal of Cu, Pb and Zn by foam fractionation and a soil washing process from contaminated industrial soils using soapberry-derived saponin: a comparative effectiveness assessment.
The present investigation indicated that the foam fractionation process is more efficient for the removal of heavy metal from contaminated industrial soil in comparison to the soil washing process. Expand
Pilot-scale washing of Pb, Zn and Cd contaminated soil using EDTA and process water recycling.
The results of the pilot-scale testing indicate that scaling-up the process to a commercial level is technically and economically feasible. Expand
Role of reducing agent in extraction of arsenic and heavy metals from soils by use of EDTA.
The results clearly showed that the combination of dithionite and EDTA can effectively extract As and heavy metals simultaneously from soils under a wide range of pH conditions. Expand
Pilot-scale washing of metal contaminated garden soil using EDTA.
Ten batches of garden soil with >50% of silt and clay were remediated in a pilot-scale chemical extraction plant and washing with 60mmol ethylenediaminetetraacetic acid per kg of soil removed 79, 38, 70, and 80% of Pb, Zn, Cd and As, respectively, and significantly reduced the leachability, phyto-accessibility and oral-availability of residual toxic metals.

Extraction of heavy metals from soils using biodegradable chelating agents.
Investigation of biodegradable chelating agents found the extraction with EDDS at pH 7 showed the best compromise between extraction efficiency for Cu, Zn, and Pb and loss of Ca and Fe from the soil. Expand
Metal associations in soils before and after EDTA extractive decontamination: implications for the effectiveness of further clean-up procedures.
After EDTA application, metal content (especially Pb) remained more weakly adsorbed to soil components (more easily leachable), potentially favouring the application of phytoremediation technologies. Expand
