Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang

Chemistry & Biochemistry Theses & Dissertations

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 …
