Cov Lus Qhia Ntxiv Ntxiv
1. Cov cai txwv tsis pub sib tw
EDTA-CaNa₂: Tsuas yog raukho mob hnyav hlau detoxification, tag nrho cov kev lag luam, khoom noj khoom haus, tshuaj pleev ib ce thiab cov kws kho mob feem ntau raug cais tawm.
EDTA-4 Na: Txwv tsis pub noj zaub mov, tshuaj qhov ncauj thiab feem ntau ntawm daim tawv nqaij - tiv tauj cov tshuaj pleev ib ce vim muaj zog alkalinity thiab khaus khaus.
EDTA-2 Na: Tsis haum rau siab -alkaline industrial systems (tsawg solubility, tsis zoo chelating nyhuv).
2. Kev xaiv ceev ceev
Tsis muaj zog acid / nruab nrab system + khoom noj / tshuaj txhua hnub / tshuaj →EDTA-2 Na
Alkaline system + industrial tu / dej kho / textile / alkaline chiv →EDTA-4 Na
Clinical lead lom tshuaj kho →EDTA-CaNa₂
