EDTA 4NA.4H2O CAS 13254-36-4
EDTA 4NA.4H2O yaj tau hauv dej thiab tuaj yeem chelated nrog ntau yam hlau ions. Hauv ntau yam pH thiab ntau yam concentration ntawm calcium-muaj dej tawv muaj peev xwm ua kom sib xyaw, thiab pH ≥ 8 ntawm qhov ua tau zoo tshaj plaws. Nrog rau 1: 1 molar piv ntawm calcium ions, nws muaj kev ruaj khov zoo hauv dej, thiab yuav tsis lwj txawm tias nyob hauv dej kub heev, thiab yog cov dej tawv mos zoo heev.
