Flow injection procedure for the determination of tertiary amines in water and sea water using chemiluminescence detection
Abstract
A flow injection procedure for the determination of triethylamine in water and sea water over the range 1 × 10–5–1 × 10–2M is described, based on measurement of the chemiluminescence emission resulting from the oxidation of triethylamine by sodium hypochlorite at pH 11.0 in the presence of Rhodamine B as a sensitiser. The response to trimethylamine, tripropylamine, ethylamine and diethylamine is also reported and a possible reaction pathway considered.
