EDTA Disodium (EDTA-2Na) | 139-33-3
Ibicuruzwa bisobanura
Acide ya Ethylenediaminetetraacetic, mu magambo ahinnye yitwa EDTA, ni aside aminopolycarboxylic aside kandi idafite ibara, amazi ashonga. Intangiriro ya conjugate yitwa Ethylenediaminetetraacetate. Ikoreshwa cyane mu gushonga limescale. Akamaro kayo kavuka kubera uruhare rwayo nka ligand ya hexadentate ("amenyo atandatu") hamwe na chelating agent, ni ukuvuga ubushobozi bwayo "sequester" ion ibyuma nka Ca2 + na Fe3 +. Nyuma yo guhambirwa na EDTA, ion zicyuma ziguma mubisubizo ariko zigaragaza ubushake buke. EDTA ikorwa nkumunyu mwinshi, cyane cyane disodium EDTA na calcium disodium EDTA.
