Description
Synonym: Total ionic strength adjustment buffer I solution
General description
TISAB, in general, is mixed with samples, as it helps in maintaining the ionic strength and pH constant. It is mainly used to decomplex metal-F complexes. TISAB I can be prepared using NaCl with glacial acetic acid, tri-sodium citrate and NaOH.
Application
TISAB I has been used in determination of fluoride-ion concentration using fluoride ion sensitive electrode. It is an ionic strength buffer, used for the determination of fluoride with ISE in the presence of Ca, Mg, Cl, etc. The pH of the solution is 2-2.5, but can be titrated to pH 5-5.5 by the use of NaOH.
Other Notes
Ionic strength buffer used for the determination of fluoride with ISE in the presence of Ca, Mg, Cl, etc.
