Abstract

Phenylfluorone reacts with zinc in the presence of hexadecylpyridinium bromide and pyridine to form a water-soluble red chelate. The absorption maximum of the chelate is at 585 nm and its absorbance is constant in the pH range 7.7-8.2. At this wavelength, Beer's law is obeyed up to 1.53 x 10(-5)M zinc. The sensitivity is very high and the molar absorptivity is 8.0 x 10(4) l.mole(-1).cm(-1). The chelate has been utilized in the determination of zinc at the microgram level. The ratio of zinc to phenylfluorone in the complex is 1:1.
