Iithegi zeMveliso

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

I-EDTA 4NA.4H2O iyanyibilika emanzini kwaye inokuchithwa ngee-ion zesinyithi ezahlukeneyo. Kwimiqolo eyahlukeneyo ye-pH kunye noxinzelelo olwahlukeneyo lwamanzi aqinileyo aqulethe i-calcium, inamandla okuntsonkotha, kwaye i-pH≥8 ikwimo ephezulu. Ngomlinganiselo we-1:1 we-calcium ions, inozinzo oluhle lobushushu emanzini, kwaye ayizukubola nokuba kumanzi ashushu kakhulu, kwaye sisithambisi samanzi aqinileyo esisebenzayo kakhulu.

Isicelo

I-EDTA 4NA.4H2O isetyenziswa njengesixhobo sokuthambisa amanzi, i-catalyst yerabha yokwenziwa, i-terminator ye-polymerization yefayibha ye-acrylic, izongezo zokuprinta kunye nokudaya, izongezo zesepha, kunye nesisombululo sokulungisa i-bleaching kwizixhobo ezinombala obuthathaka. Kuhlalutyo lweekhemikhali, ikwasetyenziselwa i-titration, ingenza i-titration ibe ngokuchanekileyo kwiindidi ezahlukeneyo zee-ion zesinyithi.
