Sharaxaada Alaabta:
Budada crystalline cad, barta dhalaalaysa 240 ° C (dalool).Aan ku milmin biyaha qabow, khamriga iyo dareerayaasha organic-ga guud, wax yar oo biyo kulul ku milmaya, ku milma xalalka sodium hydroxide, sodium carbonate iyo ammonia.
Codsiga:
(1) Waxaa loo isticmaalaa sidii bleaching iyo xalinta xalinta qalabka sawir-qaadista, kaaliyeyaasha dheeha, kaabayaasha daawaynta fiber-ka, waxyaabaha lagu daro qurxinta, dawooyinka xinjirowga lidka ku ah dhiigga, saabuunta, xasiliyeyaasha, caagga synthetic polymerisation initiators, EDTA waa walax wakiil u ah wakiilada chelating.
(2)Waxay samayn kartaa dhismayaal biyo-milmi leh oo deggan oo leh biraha dhulka alkaline, curiyeyaasha dhulka naadir ah iyo biraha kala-guurka.Marka laga soo tago cusbada sodium-ka, waxa kale oo jira cusbada ammonium-ka iyo birta, magnesium, calcium, copper, manganese, zinc, cobalt, aluminium iyo milix kale oo kala duwan, mid kasta oo ka mid ah milixyadani waxa ay leedahay adeegsi kala duwan.
(3) EDTA sidoo kale waxaa loo isticmaali karaa in lagu nadiifiyo biraha shucaaca ee waxyeelada leh ee jirka bini'aadamka iyadoo loo marayo habka qashin-saarka degdega ah.Waxa kale oo loo isticmaalaa daawaynta biyaha.
(4) EDTA waa tilmaame muhiim ah waxaana loo isticmaali karaa titrate nikkel, copper, iwm. Waa in si wadajir ah loo isticmaalo ammonia si ay u noqoto tilmaame.
