Kufotokozera Zamalonda
Ethylenediaminetetraacetic acid, yofupikitsidwa kwambiri monga EDTA, ndi aminopolycarboxylic acid komanso yopanda mtundu, yosungunuka m'madzi. Maziko ake a conjugate amatchedwa ethylenediaminetetraacetate. Amagwiritsidwa ntchito kwambiri kusungunula limescale. Kufunika kwake kumabwera chifukwa cha ntchito yake ngati hexadentate ("mano asanu ndi limodzi") ligand ndi chelating agent, mwachitsanzo, kuthekera kwake "kuchotsa" ayoni achitsulo monga Ca2 + ndi Fe3 +. Pambuyo pomangidwa ndi EDTA, ma ion zitsulo amakhalabe yankho koma amawonetsa kuchepa kwamphamvu. EDTA imapangidwa ngati mchere wambiri, makamaka disodium EDTA ndi calcium disodium EDTA.
