title: Flow injection chemiluminescence determination of polyhydroxy phenols using luminol-ferricyanide/ferrocyanide system.
abstract: It was found that the weak chemiluminescence produced from the reaction of polyhydroxy phenols with luminol in alkaline solution could be strongly enhanced by ferricyanide and ferrocyanide. Based on this found, a new flow injection chemiluminescence method is proposed for the determination of four polyhydroxy phenols: pyrogallol, phlorglucinol, quinol and resorcinol. The detection limits of the method are 0.03 mug ml(-1) pyrogallol, 0.03 mug ml(-1) phlorglucinol, 0.04 mug ml(-1) quinol, and 0.02 mug ml(-1) resorcinol. The possible mechanism of CL reactions is also discussed briefly.
