Disodium ethylenediaminetetraacetate (tseem hu ua disodium EDTA) yog ib tug muaj zog chelate agent. Vim nws qhov ruaj khov ruaj khov thiab muaj kev sib koom tes dav dav, nws tuaj yeem cuam tshuam nrog feem ntau cov hlau ions tshwj tsis yog cov hlau alkali (xws li hlau, tooj liab, calcium, magnesium thiab lwm yam ntau yam ions) chelate los tsim cov dej-soluble complexes, tshem tawm cov hlau ions lossis teeb meem tshwm sim los ntawm lawv.

Disodium EDTA yog dawb crystalline hmoov uas yog soluble hauv dej thiab yuav luag insoluble hauv ethanol thiab ether. Tus nqi pH ntawm nws cov tshuaj aqueous yog kwv yees li 5.3 thiab yog siv rau hauv cov tshuaj detergents, dyeing auxiliaries, fiber processing agents, cosmetic additives, food additives, Agriculture micro-fertilizers and Mariculture, etc.
