Potentiometric titration of alkyl aromatic sulfonates using a PVC membrane electrode
Technical Report
·
OSTI ID:5798547
A potentiometric titration method for determinig high-equivalent-weight sulfonates has been developed. This method utilizes a precipitation reaction between sulfonate and quaternary ammonium ions. A PVC (polyvinyl chloride) membrane electrode, which responds to the quaternary ammonium titrant, signals the end point of the titration. Interferences from inorganic and organic anions have been examined. Compared with the visual Methylene Blue Method, this method is faster and of comparable accuracy; it is not sensitive to the color of the sample.
