| Abstract: | A new FIA method for iso-ascorbic acid in boiler feed-water has been developed,based on the quantitative reduction of Fe3 to Fe2 by iso-ascorbic acid. 1. 10-phenanthroline was used asthe color reagent. The linear range for the determination of iap-ascorbic acid is 0-2. 0mg/L. Theproposed method has been applied to the determination of iso-ascorbic acid in boiler feed-water with good results. Recovery of 98% -102% was obtained for standard addition determination. |
