The fluorometric determination of periodate with tetraiodofluorescein has been developed. Under the optimum conditions responses were linear between 4.0×10−7 ∼ 1.0 × 10−5 mol/L of periodate. The detection limit was 1.0 × 10−7 mol/L corresponding to a signal to noise ratio of 2. The proposed method was applied to the determination of periodate in artificial fresh water and kelp sample with good results.
