Název v původním jazyce

A spectrofluorimetric determination of phenothiazine derivatives after their photooxidation or chemical or electrochemical oxidation in a flow injection arrangement

Popis výsledku v původním jazyce

A flow injection spectrofluorimetric determination of phenothiazine derivatives after their photo- or chemical or electrochemical oxidation has been developed. The determination in all the oxidation modes is based on the production of a colored phenothiazine radical-cation, which is spectrofluorimetrically detected. A bench Hg ultraviolet lamp has been used for the photooxidation of the derivatives in a simple, laboratory-made photoreactor. For the chemical oxidation of the derivatives, two strong oxidants were tested, cerium(IV) sulfate and potassium permanganate (both in acidic media). A better sensitivity has been attained with cerium(IV) ions. The electrochemical oxidation of the derivatives has been carried out continuously, in a laboratory-made thin-layer electrochemical flow-through cell. The best sensitivity and the lowest detection limit (2.6 ng/mL of chlorpromazine) have been attained with photooxidation. On the other hand, the sample throughputs of flow-injection analysis ar
