Iyini i-EDTA 4NA.4H2O nge-CAS 13254-36-4?

I-EDTA 4NA.4H2O iyancibilika emanzini futhi ingenziwa chelated ngezinhlobonhlobo ze-ion zensimbi. Kububanzi be-pH ehlukahlukene kanye nokugxila okuhlukahlukene kwamanzi aqinile aqukethe i-calcium anamandla okuba yinkimbinkimbi, kanye ne-pH≥8 ngokusebenza okuphezulu kakhulu. Ngesilinganiso se-molar ye-1: 1 ye-calcium ions, inokusimama okuhle kokushisa emanzini, futhi ngeke ibole ngisho namanzi ashisa kakhulu, futhi iyisithambisa samanzi esiqinile esisebenza kahle kakhulu.

Isicelo

I-EDTA 4NA.4H2O isetshenziswa njengesithambisi samanzi, i-synthetic rubber catalyst, i-acrylic fibre polymerization terminator, izithasiselo zokuphrinta nokudaya, izithasiselo zokuhlanza, nesixazululo sokulungisa u-bleaching sokucubungula izinto ezibucayi zombala. Ekuhlaziyweni kwamakhemikhali ibuye isetshenziselwe titration, can ngokunembile titration ezihlukahlukene ion metal.
