Ultrasonic Solubilization Technique for Use in Coulometry

Abstract

An ultrasonic solubilization technique has been developed which is useful as a first step in the coulometric determination of the chloride content of crystalline organic compounds such as p-chlorobenzoic acid.

Determination of potassium by means of the Cotlove chloridometer

“…One extension of chloridometer from the determination of free ionic chloride to organic chloride, such as organohalogen pesticides, has been reported by Czech (20) and Ferren and Fortinash (14). The same approach of appropriate prior chemical treatment and modification of the chloridometer titration solution was used by these investigators in an effort to extend coulometry into the area of "multielement chemical testing in clinical analytical chemistry," as described by Laessig (13).…”

“…The resultant convenience, low detection limit, automatic shut-off, and readout are typical of the methodolgy required for multielement testing as described by Laessig (13). A similar adaptation of the chloridometer has been described by Ferren and Fortinash (14) in the determination of organic chloride as opposed to ionic chloride.…”
