Iithegi zeMveliso

Yintoni i-EDTA 4NA.4H2O kunye ne-CAS 13254-36-4?

I-EDTA 4NA.4H2O iyanyibilika emanzini kwaye inokutshizwa ngeendidi ze-ion zetsimbi. Kwiintlobo ngeentlobo zoluhlu lwe-pH kunye nokugxininiswa okuhlukeneyo kwe-calcium-equlethe amanzi anzima anamandla obunzima, kunye ne-pH≥8 ekusebenzeni okuphezulu. Ngomlinganiselo we-1: 1 we-molar ye-calcium ions, inozinzo oluhle lwe-thermal emanzini, kwaye ayiyi kubola nakumanzi ashushu kakhulu, kwaye iyinto esebenzayo kakhulu yokuthambisa amanzi.

Isicelo

I-EDTA 4NA.4H2O isetyenziswa njenge-softener yamanzi, i-rabber synthetic catalyst, i-acrylic fiber polymerization terminator, izongezo zokushicilela kunye nokudaya, iziqholo zokucoca, kunye nesisombululo sokulungiswa kwe-bleaching ukwenzela ukusetyenzwa kwezixhobo ezibuthathaka zombala. Kuhlalutyo lweekhemikhali ikwasetyenziselwa i-titration, inokuthi iguqule ngokuchanekileyo iindidi ze-ion zetsimbi.
