EDTA Ethylene diamine tetra‐acetic acid, a compound that forms stable chemical complexes with metal ions (i.e. a chelating agent). Also called versene, sequestrol, and sequestrene. It can be used both to remove metal ions from a solution (or at least to remove them from activity) and also to add metal ions, for example in plant fertilizers.
EDTA Ethylenediaminetetraacetic acid, (HOOCCH2)2N(CH2)2N(CH2COOH)2: a compound that acts as a chelating agent, reversibly binding with iron, magnesium, and other metal ions. It is used in certain culture media bound with iron, which it slowly releases into the medium, and also in some forms of quantitative analysis.
EDTA (ethylenediaminetetraacetic acid) n. see edetate.
