ABSTRACT:
An improved flow independent method for electrochemical monitoring of a sample stream for the total concentration of a series of ionic species of the form X.sup.-n, H.sub.m X.sup.-n+m where n varies from 1 to m and X.sup.-n is an anion selected from the group consisting of fluoride ion, F.sup.-, and sulfide ion S.sup.-2. The pH of the sample stream is adjusted to a value below the pk.sub.a of the neutral most protonated species of the series. A first electrode sensitive to the activity of X.sup.-n is placed in the adjusted stream. The electric potential developed thereby is measured. A second electrode sensitive to the activity of hydrogen ion H.sup.+ is also placed in the adjusted stream. The electric potential developed thereby is also measured. The potential difference between the first and second electrode is a measure of the total concentration of the series X.sup.-n, H.sub.m X.sup.-n+m.
