✦ Synopsis

The flow-mJectlon spectrofluonmetnc determination of chlorpromazme was carried out by on-line photodenvatlzation, m which the PTFE tubing m the mJection valve loop was hehcally coded around the UV lamp An aqueous solution was used as the Earner stream The influence of foreign compounds was studied and the method was applied to the determination of chlorpromazme in pharmaceutuxl formulations

A flow-injection manifold is proposed for the on-line photochemical derivatization of thioridazine hydrochloride. The phodegradation is carried out in the coil of the injection valve, constituted of a FTFE tubing helically coiled around a UV lamp. Aqueous nitric acid was used as the carrier stream.
