Tlhaloso ea Lihlahisoa
Ethylenediaminetetraacetic acid, e khutsufalitsoeng haholo joalo ka EDTA, ke aminopolycarboxylic acid le ntho e se nang 'mala, e qhibilihang ka metsing. Motheo oa eona oa conjugate o bitsoa ethylenediaminetetraacetate. E sebelisoa haholo ho qhaqha limescale. Molemo oa eona o hlaha ka lebaka la karolo ea eona e le hexadentate ("meno a tšeletseng") ligand le chelating agent, ke hore, bokhoni ba eona ba ho "sequester" li-ion tsa tšepe tse kang Ca2+ le Fe3+. Kamora ho tlangoa ke EDTA, li-ion tsa tšepe li lula li le tharollo empa li bonts'a ts'ebetso e fokotsehileng. EDTA e hlahisoa e le matsoai a 'maloa, haholo-holo disodium EDTA le calcium disodium EDTA.
