Description

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. Visit our Sensor Applications portal to learn more.

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.
