In situ biodegradable EDDS ([S,S]-stereoisomer of ethylenediaminedisuccinic acid) applications at low concentration may present conditions where applied EDDS is insufficient relative to sorbed metals in soils. This study investigated the influence of EDDS-to-metal molar ratios (MR), solution pH and soil-to-solution ratio on metal extraction under EDDS(More)
Biodegradable EDDS ([S,S]-ethylenediaminedisuccinic acid) has been suggested for enhancing heavy metal extraction from contaminated soils. Recent studies showed that Zn and Pb are less effectively extracted due to metal exchange and re-adsorption onto the soil surfaces, especially for EDDS-deficiency conditions. This study therefore investigated the(More)
