Determination of N-chloro derivatives with a chloride-selective electrode

Abstract

A method for analysing 10^–2–10^–5M solutions of N-chlorobenzamides and other N-chloro derivatives is described. The N-chloro derivative was reduced with sulphite to release chloride and the chloride concentration was determined with a chloride-selective electrode. The method was fast and had a relative error of 1% or less throughout the concentration range studied.
