Chelating Agent:
CDTA, like EDTA, is a chelating agent, meaning it can bind to metal ions, forming complexes.
Analytical Chemistry:
It\u2019s used in analytical chemistry for the determination of metal ions, helping to prevent interference from other ions in the sample.
Decomplexing Agent in ISE Measurements:
In ion-selective electrode (ISE) measurements, particularly for fluoride determination, CDTA acts as a decomplexing agent, preventing the formation of interfering complexes with the analyte.
TISAB Solution:
CDTA is often a component of the Total Ionic Strength Adjustment Buffer (TISAB) solution, which is used to maintain a constant ionic strength during ISE measurements.
Other applications:
CDTA is also used in cosmetics, and has applications in water softening and food preservation.
