摘要：

The fluorometric determination of periodate with tetraiodofluorescein has been developed. Under the optimum conditions responses were linear between 4.0 x 10(-7) similar to 1.0 x 10(-5) mol/L of periodate. The detection limit was 1.0 x 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.
