Description

Ethylenediaminetetraacetic acid (EDTA), also known by several other names, is an aminopolycarboxylic acid and a colourless, water-soluble solid. Its conjugate base is ethylenediaminetetraacetate. It is widely used to dissolve limescale. Its usefulness arises because of its role as a hexadentate ("six-toothed") ligand and chelating agent, i.e., its ability to "sequester" metal ions such as Ca2+ and Fe3+. After being bound by EDTA into a metal complex, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA.
It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.

10.3 Possibility of hazardous reactions

Dust explosion possible if in powder or granular form, mixed with air.Behaves as a weak organic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: In the summer and winter daily cycle of a 5 kg/d load at a Swiss wastewater treatment plant, the concentration of ethylenediamine tetraacetic acid in the primary and secondary effluents was 30-150 ug/L(1). Therefore, it was concluded that ethylenediamine tetraacetic acid was not biologically degraded(1). Another study found that during the waste water treatment process, ethylenediamine tetraacetic acid was not biologically nor chemically degraded in measurable amounts(2). An enriched culture of microorganisms has been found to be an effective method for the degradation of ethylenediamine tetraacetic acid(3). Ethylenediamine tetraacetic acid, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(4).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for ethylenediamine tetraacetic acid(SRC), using an estimated log Kow of -3.86(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of ethylenediamine tetraacetic acid can be estimated to be 313(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethylenediamine tetraacetic acid is expected to have moderate mobility in soil. The pKa of ethylenediamine tetraacetic acid is 0.26(3), indicating that this compound will almost entirely exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Ethylenediamine tetraacetic acid adsorption onto lake sediment was 9, 8.6, 24.8, 21.3, 15.4 and 6.3% when complexed with sodium, copper, iron III, mercury, manganese and nickle, respectively(5). The fraction of ethylenediamine tetraacetic acid absorbed onto sediment in samples of surface waters, ground waters, and waste water treatment plant effluents from Switzerland was an average of one percent(6).
