Chelators, or chelating agents, remove heavy metals3 by binding to metal ions to form two or more bonds with their ring-like structure to build a water-soluble, stable structure. Common chelating agents include ethylenediaminetetraacetic acid (EDTA), ethylene glycol tetraacetic acid (EGTA) and ethylenediamine (Figure 2). Research has demonstrated that using chelating reagents, in combination with reducing reagents, supports in the removal of cationic heavy metals as well as anionic contaminants, such as arsenic4.
