EDTA 4NA.4H2O CAS 13254-36-4 yog dab tsi?

EDTA 4NA.4H2O yog soluble hauv dej thiab tuaj yeem chelated nrog ntau yam hlau ions. Nyob rau hauv ntau yam ntawm pH ntau thiab ntau qhov ntau ntawm calcium uas muaj cov dej nyuaj muaj peev xwm ua kom nyuaj, thiab pH ≥8 ntawm qhov ua tau zoo tshaj plaws. Nrog rau 1: 1 molar piv ntawm calcium ions, nws muaj thermal stability nyob rau hauv dej, thiab yuav tsis decompose txawm nyob rau hauv superheated dej, thiab yog ib tug zoo heev softener dej softener.
