Abstract

This thesis describes the development of a sensitive method for the separation and quantitation of organic N-chloramines in chlorinated tap water. 5-Dimethylaminonaphthalene- l-sulfinic acid has been synthesized and characterized. It yields highly fluorescent dansyl derivatives on reaction with N-chloramines. Conditions of the derivatization were optimized for the detection of N-chloropiperidine at concentrations in aqueous solution of 10-7 M. The technique gives a quantity of derivative which is proportional to the concentration of chloramine present over the range examined (10-7 M to 10-4 M). High pressure liquid chromatographic separation of dansyl derivatives of amines and amino acids has been optimized using a fluorescence detector. This technique has been applied to the analysis of tap water. Liquid chromatograms of derivatized tap water reveal the presence of many organic N-chloramines.
