Studies on the polymer + plasticizer membrane-electrode-VIII Use of the PVC + tricresyl phosphate membrane as indicating electrode in potentiometric precipitation titration.
Results obtained by use of the PVC + tricresyl phosphate membrane-electrode in potentiometric precipitation titration of some halides and pseudohalides are given. Solutions of Ag(+), Tl(+) and Hg(2)(2+) were used as titrants, to which the membrane is responsive. The fast response to Ag(+) ions allowed the determination of iodide by automatic recording of the potentiometric curve (or its derivative).
