Abstract

A novel spectrophotometric method was established for the determination of zirconium(IV) and fluoride ion. The method was based on complex formation among salicylfluorone (SAF), Zr(IV) and fluoride ion in the presence of a cationic surfactant. In the determination of Zr(IV), Beer's law was obeyed in the range of 0.09∼0.46 μg cm -3 in a neutral medium. The effective molar absorptivity at 550 nm and the relative standard deviation were 1.7 × 10 5 dm 3 mol -1 cm -1 and 0.32% (n = 6), respectively. In the determination of fluoride ion, Beer's law was obeyed in the range of 3.8∼65 ng cm -3 in a strong acidic medium. The effective molar absorptivity at 552 nm and the relative standard deviation were 2.1 × 10 5 dm 3 mol -1 cm -1 and 1.3% (n = 6), respectively.
