摘要
•Deep eutectic solvents (DESs) are used for the first time for soil remediation.•Saponins are used to enhance DESs performances for lead (Pb) removal.•Natural DESs formed with choline chloride and fructose/sucrose examined in details.•Up to 72% Pb was removed with a combination of 40% DES-fructose and 1% saponin.•Soil corrosion by DES washing is negligible.
