Ingcaciso yeMveliso:
I-crystalline powder emhlophe, indawo yokunyibilika i-240 ° C (ukubola). Ayinyibiliki emanzini abandayo, utywala kunye nezinyibilikisi eziqhelekileyo zendalo, zinyibilika kancinane emanzini ashushu, zinyibilika kwizisombululo zesodium hydroxide, sodium carbonate kunye neammonia.
Isicelo:
(1) Isetyenziswe njenge-bleaching kunye nesisombululo sokulungiswa kwezixhobo zezithombe zemibala, izixhobo zokudaya, i-fiber encedisa unyango, izongezo ze-cosmetic, i-anticoagulants yegazi, i-detergents, i-stabilisers, i-synthetic rubber polymerization initiator, i-EDTA yinto emele i-chelating agents.
(2)Inokwenza ii-complex ezizinzileyo ezinyibilikayo emanzini kunye nesinyithi somhlaba we-alkaline, izinto ezinqabileyo zomhlaba kunye neentsimbi zokutshintsha. Ukongeza kwiityuwa zesodium, kukho iityuwa ze-ammonium kunye nentsimbi, i-magnesium, i-calcium, i-copper, i-manganese, i-zinc, i-cobalt, i-aluminiyam kunye nezinye iityuwa ezahlukeneyo, nganye kwezi tyuwa zineendlela ezahlukeneyo zokusetyenziswa.
(3)EDTA ingasetyenziselwa ukukhupha iintsimbi ezinobungozi eziphuma kumzimba womntu kwinkqubo yokukhupha ngokukhawuleza. Ikwasetyenziswa njenge arhente yonyango lwamanzi.
(4) I-EDTA iyisalathisi esibalulekileyo kwaye ingasetyenziselwa ukwenza i-nickel, ithusi, njl njl. Kufuneka isetyenziswe kunye ne-ammonia ukuba isebenze njengesalathisi.
